gtsummary (development version)

• Updates to the handling of footnotes. Previously, header footnotes were handled with modify_footnote() and modify_table_styling(footnote). It was possible to also include footnotes in the table body with modify_table_styling(footnote), but this was largely a hidden feature. Also confusingly, a special abbreviation footnote was handled with modify_footnote(abbreviation=TRUE).

  In this update, we now export separate user-facing functions for each of these with clearer names and scope: modify_footnote_header(), modify_footnote_body(), and modify_abbreviation(). As the names indicate, the modify_footnote_header() and modify_footnote_body() functions place footnotes in the header and table body. Abbreviations are now treated like source notes and do not have footnote markers associated with them. We also export functions remove_footnote_header(), remove_footnote_body(), and remove_abbreviation() to remove previously assigned footnotes and abbreviations.

  Also, multiple footnotes may now reference the same cell in the table or column header by utilizing the modify_footnote_header(replace=FALSE), modify_footnote_body(replace=FALSE) argument.

• Previously, source notes were an undocumented feature and only a single source note could be included in a table. We now export modify_source_note() and remove_source_note() to add and remove any number of source notes. Also, when merging and stacking tables, previously due to the one source note limit, only the first source note was retained. Now all source notes will be included below the resulting table. This is different behavior compared to previous versions of the package and in rare cases may result in a different source note. Moreover, kableExtra output now supports source notes, where previously they were omitted.

gtsummary 2.0.4

New Features and Functions

• Added S3 methods add_overall.tbl_hierarchical() and add_overall.tbl_hierarchical_count().

• Added the tidy_wald_test(vcov) argument to allow for the calculation of p-values via alternative variance-covariance structure (e.g. for robust SEs). (#2076; @aghaynes)

Other Updates

• The with_gtsummary_theme() has been updated to no longer print theme names when the applied, nor when the original theme is re-applied. (#2031)

• Updated the theme_gtsummary_journal("jama") theme to apply changes to tbl_svysummary(). (#1964; @vjcatharine)

Lifecycle Updates

• Removed global_pvalue_fun.tidycrr(), which was previously migrated to the {tidycmprsk} package. (#1997; @jwoolfolk)

Bug Fixes

• Bug fix for footnote markers when placing a footnote for flextable and gt tables on multiple columns and rows in the table body. (#2062)

• Fix for setting default formatting functions in tbl_svysummary(). Previously, defaults were assigned similarly to those in tbl_summary(), which led to survey-only statistics being assigned sub-optimal defaults. (#2078)

• Bug fix in add_ci.tbl_svysummary() for factor variables where order was alphabetical instead of the factor levels. (#2036)

• Addressing encoding issue where sort() and dplyr::arrange() sorted differently, and the order of the by levels was inconsistent in the resulting table. (#2038)

• Users may now pass a vector of integers to tbl_hierarchical*(digits), as is possible in other summary functions. (#2080)

gtsummary 2.0.3

New Features and Functions

• Added function tbl_hierarchical(), tbl_hierarchical_count(), tbl_ard_hierarchical(), brdg_hierarchical(), and pier_summary_hierarchical(). Consider these functions as a preview. We will be making changes without the full deprecation cycle in the coming releases. (#1872)

• Adding the style_*(prefix, suffix) and label_style_*(prefix, suffix) for adding a string before or after the formatted results. These arguments have not been added to the p-value formatting functions. (#1690)

• Added argument tbl_ard_summary(overall). When TRUE, the ARD is parsed into primary ARD and the Overall ARD and we run tbl_ard_summary() |> add_overall(). (#1940)

• Added add_stat_label.tbl_ard_summary() method. (#1969)

Other Updates

• Headers in {gt} tables being exported to PDF do not support the \n line breaker. Previously, line breakers were stripped from the header in the print.gtsummary() S3 method. But this did not apply to users utilizing as_gt() to further customize their tables. As a result, the line breaking strip has been migrated to as_gt(). (#1960)

• Migrated the tbl_survfit.list(conf.level) up to tbl_survfit.data.frame(conf.level) where the confidence level is passed to survival::survfit().

• Update in tbl_ard_summary() to better handle non-standard ARDs (i.e. not our typical continuous or categorical summaries) by assigning them a default summary type. (#1991)

• Made the oneway.test() available in add_p.tbl_continuous(). (#1970)

• Removed the deprecated 'aov' test from the tests.R file listing available tests. (#1970)

• Removed documentation for the add_overall.tbl_ard_summary(digits) argument, which was never meant to be a part of this function. (#1975)

Bug Fixes

• Bug fix in add_overall.tbl_custom_summary() due to extraneous argument being passed to tbl_custom_summary(). (#2027)

• Bug fix in add_p.tbl_survfit() when the original call included tbl_survfit(type) specification. (#2002)

• Removed the "tbl_summary-arg:statistic" theme that was incorrectly added to tbl_continuous().

gtsummary 2.0.2

Updates to address regressions in the v2.0.0 release:

• The default add_glance_*(glance_fun) function fixed for mice models with class 'mira'. (#1912)
• We can again report unweighted statistics in the headers of tbl_svysummary() tables. (#1911)
• tbl_uvregression() properly handles variables specified in the include argument with non-syntactic names. (#1932)
• NA values can again be specified in add_stat_label(label) to suppress a statistic label from being placed. (#1937)
• Corrected bug in tbl_cross() where the digits argument was not always being passed accurately to tbl_summary(). (#1943)

Other updates

• The Themes and Inline Text vignettes have been converted to articles (that is, they are no longer bundled with the package, but are still available on the website).

• The total N is now returned with .$cards using the cards::ard_total_n() function for the calculation.

• The default headers for tbl_ard_*() functions no longer include counts, as these are not required data to be passed along in the ARD input.

• The summary statistics of the 'by' variable are no longer required in the ARD for functions tbl_ard_summary() and tbl_ard_continuous(). When the tabulation summary statistics are passed, they are available to place in the header dynamically. (#1860)

• The tbl_ard_wide_summary() function no longer requires the results from cards::ard_attributes() to create tables. (#1873)

• Added the label argument to functions tbl_ard_summary(), tbl_ard_wide_summary(), and tbl_ard_continuous(). (#1850)

• The add_glance*(glance_fun) argument's default value has been updated to an S3 generic, allowing bespoke handling for some regression classes. (#1822)

• Added add_overall.tbl_ard_summary() S3 method. (#1848)

• Added function tbl_likert() for summarizing ordered categorical (or Likert scales) data as well as the associated add_n.tbl_likert() S3 method. (#1660)

• Fix where error or warning condition messages containing curly brace pairs could not be printed.

• Updated the show_header_names() output to include the values that may be dynamically placed in the headers. Additionally, the include_example and quiet arguments have been deprecated. (#1696)

gtsummary 2.0.1

Updates to address regressions in the v2.0.0 release:

• Restore functionality of inline_text.tbl_summary(column) argument to specify a by level when the by variable is a factor. (#1883)
• Correct the order of the columns when the tbl_summary(by) variables has ten or more levels. (#1877)
• Re-establishing strong link between header by variable levels and those in the table body to ensure correct ordering of columns in tbl_summary().
• The tbl_survfit(times) argument accepts integers once again. (#1867)
• Fix in tbl_uvregression() for the formula argument when it includes a hard-coded column name, e.g. formula='{y} ~ {x} + grade'. The hard-coded variable name is now removed from the include argument. (#1886)
• Fix for non-Base R classes tabulated with tbl_summary() that would not coerce to character correctly after unlist(). (#1893)
• Updated the styling function from style_percent() to style_number(scale=100) when user passes an integer to change the rounding of percentages in tbl_summary(). (#1899)

Other updates

• The {tidycmprsk} dependency has been removed and the tbl_regression.tidycrr() method has been migrated to the {tidycmprsk} package. (#1865)

• The class of tbl_split() objects has been updated from "tbl_split" to c("tbl_split", "list"). (#1854)

• Updated the default value of tbl_ard_summary(missing) to "no". (#1857)

• Line breaks (i.e. '\n') are now auto-stripped from gt-rendered tables when in an R markdown or Quarto environment. (#1896)

gtsummary 2.0.0

New Features

• Clearer error messages have been introduced throughout the package. We've adopted {cli} for all our messaging to users. Our goal was to return a clear message to users for all scenarios.

• Added functions tbl_wide_summary() and tbl_ard_wide_summary() for simple summaries across multiple columns.

• The {gt} package is now the default printer for all Quarto and R markdown output formats.

  • Previously, when printing a gtsummary table in a Quarto or R markdown document, we would detect the output format and convert to gt, flextable, or kable to provide the best-looking table. The {gt} package has matured and provides lovely tables for nearly all output types, and we have now made {gt} the default table drawing tool for all gtsummary tables. These output types are still supported.

• Previously, if I wanted a single statistic to be reported to additional levels of precision in a tbl_summary() table, I would need to specify the precision of every summary statistic for a variable. Now, we can simple update the one statistic we're interested in with a named list of vector: tbl_summary(digits = age ~ list(sd = 2)).

• New functions tbl_ard_summary() and tbl_ard_continuous() have been added. These provide general tools for creating bespoke summary tables. Rather than accepting a data frame, these functions accept an ARD object (Analysis Results Dataset often created with the {cards} or {cardx} packages). The ARD objects align with the emerging CDISC Analysis Results Standard. ARDs are now used throughout the package. See below under the "Internal Storage" heading.

• The default add_global_p(anova_fun) argument value has been updated to global_pvalue_fun(), which is an S3 generic. The default method still calls car::Anova() for the calculation. Methods for tidycmprsk::crr() and geepack::geeglm() have been added that wrap aod::wald.test() as these regression model types are not supported by car::Anova().

• The add_ci.tbl_summary() S3 method has been updated with new ways to calculate the confidence interval: Wald with and without continuity correction, Agresti-Coull, and Jeffreys.

• Added a family of function label_style_*() that are similar to the style_*() except they return a styling function, rather than a styled value.

• Functions tbl_summary() and tbl_svysummary() have gained the missing_stat argument, which gives users great control over the statistics presented in the missing row of a summary table.

Internal Storage

• Greater consistency has been put in place for all calculated statistics in gtsummary. Previously, each function handled its own calculations and transforming these statistics into data frames that would be printed. Now each function will first prepare an Analysis Result Dataset (ARD), and ARDs are converted to gtsummary structures using bridge functions (prefixed with brdg_*()). The bridge functions will be exported to allow anyone to more easily extend gtsummary functions.

  • These ARDs are now used to calculate the summary statistics for nearly every function in gtsummary. The raw summary statistics are saved in .$cards.
  • Users who previously accessed the internals of a gtsummary object will find the structure has been updated, and this may be an important breaking change.

• Calculations that require other packages have been placed in another package called {cardx}. This package creates ARD objects with the calculated statistics.

• In tbl_regression(), the .$model_obj is no longer returned with the object. The modeling object is, and always has been, available in .$inputs$x.

• When the gtsummary package was first written, the gt package was not on CRAN and the version of the package that was available did not have the ability to merge columns. Due to these limitations, the "ci" column was added to show the combined "conf.low" and "conf.high" columns. Column merging in both gt and gtsummary packages has matured over the years, and we are now adopting a more modern approach by using these features. As a result, the "ci" column will eventually be dropped from .$table_body. By using column merging, the conf.low and conf.high remain numeric and we can to continue to update how these columns are formatted. Review ?deprecated_ci_column for details.

Documentation

• The vignettes "FAQ+Gallery", tbl_summary() Tutorial, tbl_regression() Tutorial, and Quarto+R Markdown have been converted to articles. The URLs on the website have not changed for these pages, but the vignettes are no longer is bundled in the package. This change allows us to provide better documentation, utilizing more tools that don't need to be included in the package.

Minor Improvements

• Argument add_p.tbl_summary(adj.vars) was added to more easily add p-values that are adjusted/stratified by other columns in a data frame.

• Messaging and checks have been improved when tidyselect is invoked in the package, i.e. when the tilda is used to select variables age ~ "Patient Age". The subset of variables that can be selected is now reduced the variables present in the table. For example, if you have a summary table of patient age (and only patient age), and age is a single column from a data set of many columns and you mis-spell age (aggge ~ "Patient Age"), the error message will now ask if you meant "age" instead of listing every column in the data set.

  • Note that as before, you can circumvent tidyselect by using a named list, e.g. list(age = "Patient Age").

• Added the following methods for calculating differences in add_difference.tbl_summary(): Hedge's G, Paired data Cohen's D, and Paired data Hedge's G. All three are powered by the {effectsize} package.

• The counts in the header of tbl_summary(by) tables now appear on a new line, e.g. "**{level}** \nN = {n}".

• In tbl_summary(), the default calculation for quantiles (e.g. statistics of the form "p25" or "p75") has been updated with type quantile(type=2).

• In tbl_summary(), dates and times showed the minimum and maximum values only by default. They are now treated as all other continuous summaries and share their default statistics of the median and IQR.

• Previously, indentation was handled with modify_table_styling(text_format = c("indent", "indent2")), which would indent a cell 4 and 8 spaces, respectively. Handling of indentation has been migrated to modify_table_styling(indent = integer()), and by default, the label column is indented to zero spaces. This makes it easier to indent a group of rows.

• The inputs for modify_table_styling(undo_text_format) has been updated to mirror its counterpart modify_table_styling(text_format) and no longer accepts TRUE or FALSE.

• The values passed in tbl_summary(value) are now only checked for columns that are summary type "dichotomous".

• The gtsummary selecting functions, e.g. all_categorical(), all_continuous(), etc., are now simplified by wrapping tidyselect::where(), which not available when these functions were originally written. Previously, these functions would error if used out of context; they now, instead,select no columns when used out-of-context.

• The design-based t-test has been added as possible methods for add_difference.tbl_svysummary() and is now the default for continuous variables.

• When add_ci() is run after add_overall(), the overall column is now populated with the confidence interval. (#1569)

• Added pkgdown_print.gtsummary() method that is only registered when the pkgdown package is loaded. This enables printing of gtsummary tables on the pkgdown site in the Examples section. (#1771)

• The package now uses updated survey::svyquantile() function to calculate quantiles, which was introduced in survey v4.1

Bug fixes

• Fix in add_difference() for paired t-tests. Previously, the sign of the reported difference depended on which group appeared first in the source data. Function has been updated to consistently report the difference as the first group mean minus the second group mean. (#1557)

Lifecycle changes

• A couple of small changes to the default summary type in tbl_summary() have been made.

  • If a column is all NA_character_ in tbl_summary(), the default summary type is now "continuous", where previously it was "dichotomous".
  • Previously, in a tbl_summary() variables that were c(0, 1), c("no", "yes"), c("No", "Yes"), and c("NO", "YES") would default to a dichotomous summary with the 1 and yes level being shown in the table. This would occur even in the case when, for example, only 0 was observed. In this release, the line shown for dichotomous variables must be observed OR the unobserved level must be either explicitly defined in a factor or be a logical vector. This means that a character vector of all "yes" or all "no" values will default to a categorical summary instead of dichotomous.

• When using the tbl_summary(value) argument, we no longer allow unobserved levels to be used unless it is an unobserved factor level or logical level.

• The quiet argument has been deprecated throughout the package, except in tbl_stack(). Documentation has been updated to ensure clarity in all methods.

• The inline_text(level) argument now expects a character value.

• The tbl_butcher(include) argument now only accepts character vectors.

• The following theme elements have been deprecated:

  • These theme elements will eventually be removed from the package: 'tbl_summary-arg:label', 'add_p.tbl_summary-arg:pvalue_fun', 'tbl_regression-arg:pvalue_fun', 'tbl_regression-chr:tidy_columns'.
    • The pvalue_fun elements should switch to the package-wide theme for p-value styling--'pkgwide-fn:pvalue_fun'.
  • These theme elements have been removed from the package immediately due to structural changes within the package: 'tbl_summary-str:continuous_stat', 'tbl_summary-str:categorical_stat'.
    • The default statistics can still be modified with 'tbl_summary-arg:statistic'

• The add_p(test = ~'aov') test is now deprecated as identical results can be obtained with add_p(test = ~'oneway.test', test.args = ~list(var.equal = TRUE)).

• Previously, add_p.tbl_summary() would coerce various data types to classes compatible with some base R tests. For example, we would convert difftime classes to general numeric before passing to wilcox.test(). We have eliminated type- and class-specific handling in these functions and it is now left to the the user pass data compatible with the functions that calculate the p-values or to create a custom test that wraps wilcox.test() and performs the conversion. This change is effective immediately.

• Arguments modify_header(update), modify_footnote(update), modify_spanning_header(update), and modify_fmt_fun(update) have been deprecated. Use dynamic dots instead, e.g. modify_header(...), which has been the preferred method for passing updates for a few years.

• Function continuous_summary() has been deprecated immediately. Apologies for the inconvenience of the immediate deprecation. The way the function originally worked is not compatible with the updated internal structures. In most cases, users can use the tbl_continuous() function instead.

• Arguments add_stat(fmt_fun, header, footnote, new_col_name) have been deprecated since v1.4.0 (2021-04-13). They have now been fully removed from the package.

• Global options have been deprecated in gtsummary since v1.3.1 (2020-06-02). They have now been fully removed from the package.

• The modify_header(stat_by) argument was deprecated in v1.3.6 (2021-01-08), and has now been fully removed from the package.

• Use of the vars() selector was first removed in v1.2.5 (2020-02-11), and the messaging about the deprecation was kicked up in June 2022. This use is now defunct and the function will soon no longer be exported.

• The as_flextable() function was deprecated in v1.3.3 (2020-08-11), and has now been fully removed from the package.

• Custom selectors all_numeric(), all_character(), all_integer(), all_double(), all_logical(), all_factor() functions were deprecated in v1.3.6 (2021-01-08), and has now been fully removed from the package. These functions were added before the tidyselect::where() function was released, which is a replacement for all these functions.

• The modify_cols_merge() functions was renamed to modify_column_merge() to match the other function names in v1.6.1 (2022-06-22). The deprecation has been upgraded from a warning to an error.

• There is a change in the theme_gtsummary_journal("qjecon") theme for gt output. The journal prefers to present regression coefficients above their standard errors. To achieve this placement in gt table, we were taking advantage of a bug or feature (depending on your point of view) that allowed this placement when a gt table was output to HTML and HTML only. The gt package is now working on a proper solution for linebreaks within a cell, and until that feature is active, we are not using our hack. There is no change for this theme for the other tabling engine packages.

gtsummary 1.7.2

• Removed messaging about the former auto-removal of the tbl_summary(group) variable from the table: a change that occurred 3+ years ago in gtsummary v1.3.1

• Fix in as_flex_table() where source notes were not accurately rendered. (#1520)

• Fix in column order when add_ci() is run after add_overall(last=TRUE). Previously, the overall columns were placed in front. (#1525)

• Line breaks (i.e. \n) are now removed from column headers and table cells when as_kable() is called. (#1526)

• Fix in as_gt() where columns with common spanning headers were gathered. Corrected with gt::tab_spanner(gather = FALSE). (#1527)

• Fix in remove_row_type() where header rows for continuous2 type variables was not removed when requested. (#1507)

• Fix where some default add_p.tbl_summary() categorical tests were chi-squared when it should have been Fisher's exact test. This misclassification occurred in some cases when there was a large differential in the missing pattern for one of the variables in the cross table. (#1513)

• Fix in add_overall(col_label=) where specified label was not always placed. (#1505)

gtsummary 1.7.1

New Functions

• Added as.data.frame() S3 method for gtsummary class.

New Functionality

• The tbl_svysummary() function may now report the design effect, e.g. tbl_svysummary(statistic = ~"{deff}"). (#1486)

• Added French translations for new marginal effects tidiers housed in {broom.helpers}. (#1417)

• Added theme elements to control the default headers in tbl_svysummary(). (#1452)

• Improved error messaging in tbl_uvregression() when method= argument is not correctly specified. (#1469)

• Updates to account for changes in {forcats} v1.0.0 and {dplyr} v1.1.0.

• tbl_svysummary() can now report design effects (#1486)

Bug Fixes

• Fix in the footnote of add_overall() when run after tbl_continuous(). (#1436)

• Updating the levels of precision used in round2(), which is used in the background for every rounded/formatted number in a gtsummary table. (#1494)

• Bug fix when a subset of CIs are requested in add_ci(include=). (#1484)

• Update in as_hux_table() to ensure the Ns in header are not incorrectly auto-formatted by {huxtable}.

• Fix in the style_*() family of functions. The attributes of the input vector--excluding the class--are retained. (#1460)

• Updated style_ratio() to now format negative values.

• Bug fix in add_ci.tbl_svysummary() for dichotomous variables.

• add_ci.tbl_svysummary() now takes properly into account the percent argument (#1470)

gtsummary 1.7.0

Breaking Changes

• Updated the default argument values in tidy_robust(vcov=NULL, vcov_args=NULL). Users must specify the type of robust standard errors using these arguments.

• Fully removed deprecated items that were originally deprecated in v1.2.5 (released 3 years ago).

  • add_p(exclude=), as_gt(exclude=), as_kable(exclude=), as_tibble.gtsummary(exclude=), tbl_regression(exclude=), tbl_uvregression(exclude=)
  • tbl_summary_(),add_p_()
  • add_global_p(terms=)

New Functions

• New function add_ci.tbl_svysummary() for adding confidence intervals to tbl_svysummary() summary statistics. (#965)

New Functionality

• Arguments pass via the dots in tbl_uvregression(...) are now passed to broom.helpers::tidy_plus_plus(...). (#1396)

• Added new theme elements to control the default headers in tbl_summary(). (#1401)

• All examples that previously used <br> for line breaks in gt tables have been updated to use \n. Additionally, the "qjecon" journal theme has been updated to use the updated line breaker as well. (#1311)

• Now allowing for mixed-class numeric types in tbl_summary(), such that inline_text() will not throw an error when the pattern argument is specified.

• Added stats::mood.test() to add_p.tbl_summary(). (#1397)

New Documentation

• Added a new article illustrating how to place gtsummary tables into Shiny applications. (#1335)

Bug Fixes

• Updated Lancet journal theme to report p-values with more precision, per the journal's reporting guidelines. (#1442)

• Fix for as_flex_table() when the header is blank. (#1406)

• Fix in tbl_summary() that now allows for column vectors to be named within a data frame. (#1403)

gtsummary 1.6.3

• The as_flex_table() function now recognizes markdown bold (**) and italic (_) syntax in the headers and spanning headers. Restrictions apply. See help file for details. Users can no longer place sets of double stars and underscores without the text being formatted as markdown syntax. (#1361)

• The modify_caption() function now works with tables created with gtreg::tbl_listing() that do not contain a column named "label". (#1358)

• Functions tbl_summary() and tbl_svysummary() now support "{n}", "{p}", and "{level}" when no by= variable is present for use in functions like modify_header(). For example, the following previously invalid code works well for both the overall column and the stratified columns:

  trial %>%
    tbl_summary(by = trt) %>%
    add_overall() %>%
    modify_header(all_stat_cols() ~ "**{level}**, N = {n}")

  For the survey summary, the unweighted variants are also available. (#1366)

• Added experimental feature where additional arguments can be passed to broom.helpers::tidy_plus_plus() via tbl_regression(...). (#1383)

• Updated the arguments in tidy_robust() to account for updates in {parameters}. (#1376)

• Allowing for 'survfit' objects of class survfit2 in add_nevent.tbl_survfit(). (#1389)

• Added oneway.test() test to add_p(). (#1382)

• Now using {ggstats} to plot regression model coefficients via plot() instead of {GGally}. (#1367)

• Bug fix in tbl_custom_summary(): the full dataset (including missing observations) is now properly passed as full_data (#1388)

gtsummary 1.6.2

• The following updates were made to the indentation implementation for gt output:

  • Previously, only HTML output was able to indent for gt tables, and this was implemented via gt::tab_style().
  • Indentation is now available for HTML, PDF, and Word and is implemented by adding unicode non-breaking spaces to the data frame via gt::text_transform().
  • The "names" for the indentation calls have been updated to "indent" and "indent2". This change should affect very very few users. If you're not sure what the names refer to, then this does not affect you.
  • Indentation for RTF does not currently work. Instead of indented columns, irregular unicode characters are shown. This issue will be addressed in a future gt release. If you do use RTF output, and would like your output to be identical to what it was before this update, use as_gt(include = -indent).

• A link to the cheat sheet has been added to the website's navigation bar.

• Added additional options to remove_row_type(type = c("level", "all")).

  • Use type = "all" to remove all rows associated with the variable(s) specified in remove_row_type(variables=).
  • Use type = "level" in conjunction with new argument level_values= to remove specified levels for a variable, or do not use the new argument to remove all levels for categorical variables.

• Added the standard error of means to the list of available statistics for continuous data summaries in tbl_svysummary(). (#1291)

• Added Dutch language translations. (#1302)

• Updated add_significance_stars() to accept any gtsummary table (instead of only regression model summaries) and to work with add_global_p() (#1320)

• Added the "var_type" hidden column to the output of tbl_survfit(). This addition ensures the table will work with remove_row_type(). (#1343)

• Updated calls to round() in the style_*() functions to round2(), which implements classic rounding rules. (#1304)

• Fixed bug in style_sigfig() with numbers close to the thresholds. (#1298)

• Fixed bug when a column named "variable" was passed to tbl_custom_summary(by=), which resulted in an error. (#1285)

• Bug fix in as_tibble(fmt_missing = TRUE). Previously, missing assignments applied to more than one row were being ignored. (#1327)

• Bug fix in column alignment with tbl_stack() for as_kable_extra() output. (#1326)

gtsummary 1.6.1

New Functionality

• Added the standard error of proportions to the list of available statistics for categorical data summaries in tbl_svysummary(). (#1187)

• Added Tarone-Ware test to add_p.tbl_survfit() (#732)

• Updated add_global_p() to handle tbl_uvregression() objects where users specified the x= argument (when y= argument is more common). (#1260)

Other Updates

• Updated start-up messaging. (#1228)

• The paired.wilcox.test available in add_p.tbl_summary() and add_difference.tbl_summary() was mistakenly marked as returning a difference, but it does not. The documentation has been corrected, which results in improved messaging to the user when the test is selected in add_difference(). (#1279)

• Improved error messages for paired tests in add_p() and add_difference() when group= argument is not specified. (#1273)

• Added argument with_gtsummary_theme(msg_ignored_elements=) argument. Use this argument to message users if any theme elements will be overwritten and therefore ignored inside the with_gtsummary_theme() call. (#1266)

• Swapped gt::fmt_missing() for gt::sub_missing() as the former is now deprecated. (#1257)

• The checks for "haven_labelled" class are now only performed for the variables indicated in include= and by= in tbl_summary() and tbl_svysummary(). The checks in tbl_uvregression() and tbl_survfit.data.frame() are only applied to the variables in include=, e.g. no checking for the outcome variable(s).

• Updates to labels and default formatting functions of unweighted statistics presented in tbl_svysummary(). (#1253)

• Adding additional structural checks in tbl_merge() and inline_text() to provide better error messaging. (#1248)

• Added tbl_regression.crr() method with messaging recommending use of tidycmprsk::crr() instead. (#1237)

• The experimental support for ftExtra::colformat_md() in as_flex_table() has been removed. The function requires evaluated YAML paths and does not allow un-evaluated references like bibliography:: "`r here::here()`". (#1229)

• Update for tbl_summary(by=) that now allows for a column named "variable" to be passed. (#1234)

• Added theme element to control what missing statistic is shown in summary tables with options to display number or percent missing or non-missing or total number of observations. (#1224)

• Renamed modify_cols_merge() to modify_column_merge() to be inline with the other modify_column_*() functions.

Bug Fixes

• Fix in as_kable_extra() when output format is 'latex' where a cell that had been bold or italicized had special characters double-escaped. Added a condition not to escape special characters in these styled cells. (#1230)

• Fix in with_gtsummary_theme(). The function restored any previously set theme, but inadvertently included the temporary theme along with it.

gtsummary 1.6.0

Improvements to as_kable_extra()

• For users who used the default kableExtra print without output-specific formatting, there are no breaking changes...the only changes will be improved output styling.
• The biggest user-facing change is that the default results for LaTeX output are now greatly improved compared to previous releases, when escape=FALSE (the new default).
  • Markdown bold, italic, and underline syntax in the headers, spanning headers, caption, and footnote will be converted to escaped LaTeX code.
  • Special LaTeX characters in the body of the table will be escaped with .escape_latex() or .escape_latex2(), e.g. % will be updated to \\%, and rendered as % in the PDF document.
  • The "\n" symbol will be recognized as a line break in the table headers, spanning headers, caption, and the table body.
  • \n is removed from footnotes
  • The escape= argument is now passed to kableExtra::add_header_row() and kableExtra::footnote() as well (previously, was only passed to knitr::kable()).
• The as_kable_extra(escape=, format=) arguments have been made explicit, where previously, these arguments were passed via ....
• Breaking Change The default value of escape= is now FALSE. If users previously used as_kable_extra(escape=FALSE) and had manually escaped LaTeX/HTML characters in the body of the table, these characters will now be double escaped. To print the table without the auto-escaping that is now present, utilize the new argument as_kable_extra(addtl_fmt=FALSE)
• Breaking Change The fmt_missing= argument was added to as_tibble(), as_kable(), and as_kable_extra() in the last release. This argument is now deprecated in as_kable() and as_kable_extra(). If a user does not want missing values formatted, they can exclude these commands with the include= argument.
• Breaking Change The strip_md_bold= has been deprecated. The markdown syntax will automatically be stripped from headers, unless escape = FALSE and format = "latex". In that case, the markdown syntax will be converted to LaTeX commands.
• HTML Updates
  • The default markdown syntax in the headers and spanning headers is removed.
  • Special characters in the table body, headers, spanning headers, caption, and footnote will be escaped with .escape_html().
  • The "\n" symbol is removed from the footnotes

Improvements to as_flex_table()

• Added support for markdown syntax in {flextable} header rows by utilizing the {ftExtra} package. If this package is installed and options(gtsummary.use_ftExtra = TRUE) has been set (or the equivalent theme element), the bold/italic markdown syntax found in the headers will be styled. Otherwise, the markdown syntax is stripped from the header rows. (#1200)

New Functions

• New function as_hux_xlsx() added to export a formatted {gtsummary} table directly to Excel.

• Added a tbl_regression.tidycrr() method to summarize competing risks regression models. (#1169)

• Added tidier tidy_wald_test(), a generic function that can calculate Wald test statistics for groups of variables in a model. The tidier expects the model object is supported by both vcov() and coef() to obtain the variance-covariance matrix and the coef vector.

• Adding functions get_gtsummary_theme() and with_gtsummary_theme() for extracting the current gtsummary theme and running code with a temporarily theme.

• Added new function modify_column_indent()--a wrapper for modify_table_styling()--to make it easier to add and remove indentation in a table.

• Now exporting a function primarily used internally as a helper for converting a gtsummary table to gt (and other formats): .table_styling_expr_to_row_number().

• Theme helper function check_gtsummary_theme() has been added. The function takes a gtsummary theme list as the input, and runs various consistency checks. Useful when constructing a personalized theme. This function replaces the internal checks that a passed theme element is indeed a valid theme element.

New Functionality

• Functions bold_labels(), bold_levels(), italicize_labels(), italicize_levels() are now method functions so they can work better on tbl_cross() objects.

• Total overhaul to the way statistics are saved and reported in modify_header(), modify_spanning_header(), modify_footnote(), and modify_caption(). There is now a standardized place to these statistics to be saved in all gtsummary tables (in x$table_styling$header in columns starting with "modify_stat_"). The modify functions have been updated to access the statistics from the header data frame. An added benefit to this structure, is that the statistics are available after tables are merged and stacked. Statistics available in modify_caption() are taken from the "label" column. (#1165, #1101)

• Added add_global_p(anova_fun=) argument allowing users to pass custom functions to calculate global p-values when car::Anova() does not support the model type. (#1149)

• Functions bold_labels(), bold_levels(), italicize_labels(), and italicize_levels() now bold/italicize the first column shown in the table. Previously, the "label" column (which is most often the first shown column) was styled.

• Added theme element to pass arguments to knitr::kable() in as_kable() and as_kable_extra().

• Updated the default function in add_glance_*(glance_fun=) for MICE models. (#1137)

• Add tbl_butcher(keep=) argument to optionally keep some internal objects as needed. (#1148)

• Adding Norwegian translations (#1143)

Other Updates

• Removed use of round() in style_number(), and replaced it with a round function that does not "round-to-even". (#1140)

• Converted the Table Gallery vignette into an FAQ+Gallery (#811)

• Added error messaging if user tries to run add_p() or add_difference() twice. (#1209)

• All models CIs were labelled as a Confidence Interval. Now Bayesian models will correctly label the Credible Interval. (#1196)

• Improved error messaging the functions as_gt(), as_kable(), as_flex_table(), as_hux_table() when an object that is not class 'gtsummary' is passed. (#1188)

• Deprecated the as_huxtable(strip_md_bold=) as {huxtable} now recognizes the markdown syntax and there is no reason to remove the markdown syntax.

• Added huxtable::set_header_rows() to the as_hux_table() stack.

• Improved error messaging in modify_*() functions. (#914)

• Added style_percent() as the default formatting function for un-weighted proportions. (#1181)

• The global options previously available have now been soft deprecated. All documentation of the global options was removed in v1.3.1. (#1085)

• The as_flextable() function has been upgraded from a soft to a hard deprecation; use as_flex_table() instead.

• No longer removing the survey design columns from survey objects from the columns that will be summarized in tbl_svysummary() and those summarized in tbl_uvregression(). If users previously didn't indicate which variables to summarize with include=, then the design columns will now appear in the summary tables. (#1166)

• Added a check for functions that accept ... where nothing should be passed in the .... If a bad or misspelled argument is found, the users are informed. (#1083)

Bug Fixes

• Fix in "emmeans" methods for add_difference() to due an argument name change in the emmeans package. We now require the most recent version of the package. (#1205)

• Bug fix in inline_text.tbl_summary() where one could not pass a pattern only when the column argument was NULL. (#1193)

• Fix in as_gt() when there are no hidden columns.

• Fix in add_p.tbl_svysummary() when Wald tests were converted to flextable. The survey tidier saved the column as a matrix-column instead of a vector, which was incompatible with flextable output. (#1153)

• Fixing Lancet theme mid-point encoding issue on Linux and MacOS. (#1146)

• Fix when using summary type gtsummary selectors (e.g. all_continuous()) with the add_ci(style_fun=) argument. (#1141)

gtsummary 1.5.2

• Removed foreign reference to external functions in the top level of the package and replaced with indirect calls (the reason for the short time between releases). (#1129)

• Updates to the way footnotes are printed in tbl_summary() when there is summary type "continuous2" present. Previously, all footnotes were removed, and now only the "continuous2" footnotes are removed. (#1127)

• Added the continuous variable name/label to the footnote for greater clarity in tbl_continuous() (#1123)

• Now exporting the .create_gtsummary_object() function as a utility for other packages to build gtsummary tables. (#1130)

• Fix when add_overall() was run before add_n(). The overall row was not being omitted from the sum and the Ns were doubled. (#1126)

• Added method "emmeans" to add_difference() for tbl_svysummary() objects.

• Updated default add_difference() for tbl_svysummary() objects to be "emmeans" for continuous and dichotomous variables, and "smd" for categorical variables.

gtsummary 1.5.1

New Functions

• Added new function modify_column_alignment() to updated column alignment. Function is a wrapper for the more complex modify_table_styling() function.

• New function tbl_strata2() that passes both the the stratified data frame as well as the stratum level to the user function. (#1091)

• Added a add_p.tbl_continuous() method for adding p-values to tbl_continuous() tables. (#1023)

• Added add_overall.tbl_continuous() method. (#1037)

New Functionality

• New test option "emmeans" in add_difference() and add_p() uses the {emmeans} package to estimate marginal means/least-squares means for continuous variables, binary variables and random intercept models. (#1112)

• Column alignment is now recognized in as_kable() and as_kable_extra(). Previously, the alignment utilized the kable() defaults and ignored any alignment instructions included in the gtsummary table styling.

• The as_kable_extra() was updated to utilize kableExtra::column_spec() and kableExtra::cell_spec() to apply bold and italic styling. The choice of the function depends on the use of escape= in knitr::kable() (#1107)

• Default arguments to knitr::kable() may now be overwritten by passing ... to either as_kable() or as_kable_extra(). Previously, passing a user-defined argument previously in use would result in error.

• Added tbl_strata(.header=) argument providing greater control over the stratum headers that are added to the tables, e.g. you can now add Ns to the headers using this argument.

• Added add_p.tbl_cross(test.args=) argument. (#1095)

• The tbl_strata(.combine_args=) has been added that lets you control all arguments in the tbl_merge() or tbl_stack() that occurs in tbl_strata(). (#1090)

• Added the add_ci(pattern=) argument, which makes it easier to merge the CI column with the primary statistics column. (#1029)

• Suppress tbl_merge() spanning headers by passing tbl_merge(tab_spanner = FALSE) (#1067)

• Functions as_tibble(), as_kable(), and as_kable_extra() gain the fmt_missing= argument that applies missing symbols to missing values. The as_tibble() argument defaults to FALSE, while the others' default is TRUE. (#1073)

• Adding tbl_regression(conf.int=) and tbl_uvregression(conf.int=) argument. For some models, the confidence interval adds to the computation time significantly and may not be needed. This argument will omit the CI calculation. (#1052)

• The add_stat() function was updated to accept tbl_continuous() tables.

• Multinomial models computed using MICE are now supported. (#1065)

• Added theme element to control the tbl_regression(conf.int=) default argument.

• It is now possible to pass a single tbl to tbl_merge(). This is useful when using tbl_merge() as a helper in other functions. (#1068)

• Added statistics= and digits= arguments to the add_overall() family of functions. (#1047)

• Added digits= argument to tbl_cross(). (#1046)

Other Updates

• Allowed modification to font_size for compact theme. (#1106)

• Automatically reduced vertical white space between columns for compact flextable theme.

• Improved user interface for modify_*() functions (#1064)

• Improved error messaging throughout the package. (#1050)

• Added link to the syntax help file to functions throughout the package. The syntax help file illustrates how to use the gtsummary selectors and details the formula-list notation. (#981)

• Updated Spanish translation for Wilcoxon Rank-sum Test.

• Updates and additions to Portuguese language translations. (#1098)

• Updates to the French translations.

• Updating the add_overall() S3 method to have a more common structure, e.g. add_overall(x, ....), where previously, the ... were not present. (#1066)

• Updated the theme_gtsummary_journal("qjecon") to set tbl_regression(conf.int = FALSE) by default.

• Improved error messaging in tbl_custom_summary()

• Updated the default formatting functions in tbl_custom_summary(). Previously, summaries with character results erred because the default summary function was style_number(). This has been updated to style_sigfig() for numeric columns, and as.character() for everything else. (#983)

• All style_*() functions will retain attribute, such as the names. (#1035, #1031, #981)

• The add_n.tbl_regression() (which is also utilized in tbl_uvregression()) was adding the N column without applying a formatting function. The style_number() function has now been added as the default styler. (#1022)

• Added class "tbl_continuous" to the output of tbl_continuous().

• Adding add_p() test "mcnemar.test.wide" to calculate the p-value when the data are stored in a wide format, e.g. one column for a before value and a second column for after. The other McNemar test variant available in {gtsummary} expects data in a long format.

• Converted tbl_split() to S3 function.

• Update how calls to gt::fmt_missing() are constructed to be more memory efficient.

Bug Fixes

• Fix in add_significance_stars() that led to an error when the summarized model did not have a confidence interval column.

• Fix in as_flex_table() and as_hux_table() where reference row was not properly placed after a tbl_merge() when the merged tables share common categorical variables but different reference rows. (#1063)

• Fix in inline_text.gtsummary() where the first level of a categorical variable could not be selected if the table had also been processed with remove_row_type(). (#1078)

• Fix in modify_table_styling(cols_merge_pattern) when it is used with tbl_stack() followed by tbl_merge(). (#1057)

• Bug fix in separate_p_footnotes() where test names were not being translated when theme_gtsummary_language() was set. (#1055)

• Fix in tbl_merge() when rows in a merging table are not present in the first table. (#1033)

• Fix in as_tibble() for nnet::multinom() regression models.

• Fix in tbl_continuous() when include= is not specified.

• Fix in tbl_regression() when a tidier returns CI columns that are all missing. (#1012)

• Fix in add_p()/add_difference() when check whether the passed test is an internal method or a custom method. The previous code required Suggested packages, such as, {lme4}, {effectsize}, and {survey}, to be installed. (#1018)

Breaking Changes

• No longer exporting assert_package(). It has been migrated to {broom.helpers} and we now use broom.helpers::.assert_package(). (#1051)

gtsummary 1.5.0

New Functions

• Added new function tbl_continuous() to summarize a continuous variable by 1 or more categorical variables.

• Added new function add_ci() that adds a new column with the confidence interval for proportions/means reported in tbl_summary(). (#868)

• Migrated a new function tbl_split() from the {bstfun} package. Function allows users to split a {gtsummary} table into multiple tables.

• Migrated a new function separate_p_footnotes() from the {bstfun} package. Function allows users to separate the composite footnote listing the tests performed in add_p(), and replaces it with individual footnotes for each test name.

• New function tbl_custom_summary() allowing to create a table of summary statistics using a custom summary function (#973, #976)

  • Set of helpers to be used with tbl_custom_summary(): continuous_summary(), proportion_summary(), ratio_summary()

• New function modify_cols_merge() that can merge two or more columns in a {gtsummary} table. (#939)

• Added function tbl_butcher() to reduce the size of a {gtsummary} table. After an object has been butchered, other {gtsummary} functions may not be able to execute on the object.

• Added new function tidy_robust() that will add robust standard errors, confidence intervals, and p-values with tbl_regression() and tbl_uvregression(). The function is a wrapper for parameters::model_paramters(). (#979)

New Functionality

• Added a CITATION file so users can now cite the R Journal manuscript using citation("gtsummary").

• Added Standardized Mean Difference method to add_difference(), wrapping the {smd} package's calculations. (#966)

• Extended add_difference() to accept tbl_svysummary() objects in addition to tbl_summary() objects.

• Added a standardized mean difference method for tbl_svysummary() tables.

• Added tbl_strata(.stack_group_header=) argument to include/exclude the headers when tables are combined with tbl_stack()

• Added tbl_strata(.quiet=) argument.

• Allow add_p() and add_difference() to be run on the same table. (#959)

• Updated add_overall() to include the overall statistics in the df_stats tibbles saved in .$meta_data. This makes it possible to report any of the overall statistics using the inline_text(pattern=) argument.

Other Updates

• Added a help file detailing the formula list notation used throughout the {gtsummary} package. (#981)

• Updates to tbl_regression() documentation. The model N is no longer reported by default, and removed that section from the help file. (#998)

• Updates to make the internal df_stats objects consistent across various {gtsummary} objects. Added internal function df_stats_to_table_body that adds the numeric df_stats tibble to .$table_body. The formatting functions are also added for the new columns to .$table_styling$fmt_fun. This function is now used in inline_text.gtsummary() to prepare the returned statistics (#921)

• Now using broom::tidy() to prepare the car::Anova() results. This will be more stable than the version originally written. (#898)

• The function assert_package() now takes the minimum required version of the package from the DESCRIPTION file, and the function is now exported.

• Now using broom::tidy() to prepare aov() test results in add_p.tbl_summary(), which adds additional columns to .$table_body() (#956)

• Updated the README to include links to a recording of a gtsummary presentation and to the RStudio Education blog post.

• Removed maturing lifecycle tag from README.

• Updated deprecated function workflows::pull_workflow_fit(x) to workflows::extract_fit_parsnip(x).

Bug Fixes

• Fix in tbl_summary() when a factor variable is passed that is all NA with no specified levels. (#977)

• Fix in add_p.tbl_summary() when a factor variable with all NA values is passed. (#977)

• Bug fix for the add_difference(estimate_fun=) argument.

Breaking Changes

• Updated add_p.tbl_summary(test = . ~ "mcnemar.test", group = id) syntax to require the group= argument to align with the paired Wilcoxon rank-sum test and paired t-test syntax.

• Deleted deprecated functions add_comparison(), add_global(), tab_style_bold_p(), tab_style_bold_labels(), tab_style_italicize_levels(), tab_style_italicize_labels(), tab_style_bold_levels().

• The following deprecated arguments have been removed: tbl_summary(group=), as_gt(omit=).

• The survival package has been moved from Imports to Suggests, and will no longer automatically be installed when {gtsummary} is installed. Additionally, survival::Surv() is no longer re-exported with the package.

gtsummary 1.4.2

• Update to the internals of tbl_stack() to better handle when two or more stacked tables are then stacked again (#906)

• Updates to make tbl_svysummary() compatible with {survey} package updates in v4.1 (#930)

• The as_hux_table() function previously stripped markdown old syntax from column headers and spanning headers. The output now uses markdown syntax in the headers by default utilizing huxtable::set_markdown() (#885)

• Variables passed in the tbl_svysummary(by=) argument will now automatically be added to include=. (#925)

• Bold and italic requests are now ignored for kableExtra output. These are carried out via markdown syntax, which is not supported by {kableExtra} (#917)

• Bug fix for add_p.tbl_cross(pvalue_fun=); argument was being ignored.

• Updated style_pvalue() to format p-values slightly larger than 1 and slightly lower than 0 (due to imprecise numeric storage). (#907)

• Fix allowing for factor vectors to be passed in tbl_stack(group_header=). (#908)

• Updated arguments y= and x= in tbl_uvregression() to allow for non-standard names (#912)

gtsummary 1.4.1

• Updated tbl_regression() to be compatible with models created with the {parsnip} and {workflows} packages (#890, #647)

• Added the modify_table_styling(text_format = "indent2") option to double indent a row. (#864)

• Messaging update when inline_text.gtsummary() suspects a variable has been repeated in the gtsummary table. (#855)

• Bug fix in add_p.tbl_summary() for columns that are all NA. These variables no longer error; rather, a message is printed indicating the p-value is not possible to calculate. (#889)

• Updated tbl_svysummary() to be compatible with {srvyr} package (#886)

• Updated default header when using tbl_uvregression(x=) to "**Outcome**" (#867)

• The tbl_summary(by=) variable is now added to include= by default (#871)

• Bug fix for {Hmisc} labeled data with tbl_summary() (#876)

• Bug fix in add_n.tbl_summary() to proportion missing in some cases. (#903)

• Updates to the default formatting functions in the add_glance_*() functions. P-values are now styled with style_pvalue() and No. Obs. and degrees of freedom with style_number() (#870)

gtsummary 1.4.0

New Functions

• Added new function add_glance_table() as a companion to add_glance_source_note(). Function adds model statistics, such as R-squared, to the bottom of the model summary table.

• Added new function add_significance_stars() adding star indicators to significant estimates and an explanatory footnote.

• Added new function tbl_strata(). The function aids prepares gtsummary tables stratified by one or more variables (#679)

• Adding coefficient plot() methods for tbl_regression() and tbl_uvregression(). Function creates a forest plot of model coefficients via GGally::ggcoef_plot().

• New function modify_fmt_fun() has been introduced to help update the functions that format numeric columns and rows in .x$table_body.

• New function introduced, modify_table_styling(), to update printing instructions of tables. This function replaces modify_table_header(), which is now soft deprecated.

• Added function add_vif() to include variance inflation factors in tbl_regression() output. (#717)

• Added a generic function inline_text.gtsummary() that can report results from any gtsummary table. (#398)

New Functionality

• Print infrastructure has been updated to allow for both row and column specification when formatting data or table styling. The x$table_header object has been replaced with a more general x$table_styling. Review the updated vignette "gtsummary_definition.Rmd" for details. The x$table_body is no longer grouped after tbl_stack(); rather, the grouping variable is specified in gt::gt(groupname_col=)

• tbl_summary() now accepts any class as input. Previously only non-date base classes were accepted. For non-base R classes, the summary type must be specified using tbl_summary(type=). The default summary statistic for dates/times is the minimum and maximum. (#488)

• The add_stat() function may now return multiple columns of new statistics. Some arguments have been deprecated in the update. (#746)

• tbl_uvregression() now accepts both data frames and survey design objects as input. (#742)

• If the default tidy_fun = broom::tidy fails, parameters::model_parameters() attempts to tidy the model, if {parameters} is installed. (#854)

• Added a custom tidier for mgcv::gam() models (tidy_gam()) and a method function (tbl_regression.gam()) that uses the new tidier by default. (#745)

• Added default support for brmsfit model in tbl_regression() with new method function. (#751)

• Functions modify_footnote() and modify_spanning_header() now include the text_interpret= argument indicating whether to use gt::md() or gt::html() to format text. Default is gt::md().

• Added/updated functions add_n() and add_nevent() to work with tbl_regression and tbl_uvregression objects. Each function now has an argument to place Ns on the label or level rows. (#744)

• Added The Quarterly Journal of Economics to theme_gtsummary_journal(). This journal theme will be updated again after the gt package updates cols_merge() with a rows argument and allows for line breaks within cell.

• Korean and Icelandic language translations added for theme_gtsummary_language().

• Ability to merge two or more columns with modify_table_styling(cols_merge_pattern=) argument.

• Added theme element "pkgwide-fun:pre_conversion". The function specified here will be executed on the gtsummary object before it is printed or converted with the as_gt(), as_flex_table(), etc functions. (#773)

• The modify_table_body(fun=) argument has been generalized to accept formula shortcut notation.

• Added exploratory data analysis theme that shows more details by default, theme_gtsummary_eda().

Other Updates

• Updated tbl_merge() and tbl_stack() to capture the first source note and caption in the merged/stacked tables. Previously, any captions and source notes were lost.

• Added messaging when table caption requested via modify_caption() for a gt table when using a version of gt that does not support captions.

• Updates to the table gallery vignette reflecting changes in the package. (#775)

• Improved error messaging when there is a problem constructing one of the univariate regression models in tbl_uvregression().

• Added variable-specific formatting to add_difference(estimate_fun=) allowing a single table to show, for example, mean and rate differences that are formatted/rounded differently.

• Improved handling and messaging to users when columns with "haven_labelled" class are passed to gtsummary functions. (#805)

• Improved handling of ordered factors as the by= variable (#569, #540)

• Removed {usethis} package dependency and replaced with {cli}. (#768)

• Added the survey-adapted t-test to theme_gtsummary_mean_sd() for continuous variables in add_p.tbl_svysummary() (#758)

• Allowing for tidyverse shortcut notation in tbl_survfit(estimate_fun=) specification, e.g. tbl_survfit(estimate_fun= ~style_sigfig(.x * 100)) (#761)

• The JAMA journal theme has been updated to merge the coefficient and confidence interval columns.

• Updated other inline_text() functions to wrap inline_text.gtsummary()

Bug Fixes

• The label= argument for unstratified models was being ignored in tbl_survfit() (#842)

• Preserve ordering for factor variables in tbl_survfit(). (#764)

• Bug fix for spanning headers with kableExtra output. The spanning header was misplaced when the header text was sandwiched between two blank spanning headers.

• Bug fix when displaying an unobserved level of a factor variable dichotomously in tbl_summary(). (#780)

• Bug fix in add_p() where test name footnote was not being translated with theme_gtsummary_language().

Breaking Changes

• tbl_survival() has moved from questioning to deprecated. This function maintains the old x$table_header format (instead of the more flexible x$table_styling). The "level_label" column was renamed to "groupname_col" and the x$table_body is no longer grouped with group_by(level_label)

• The back-end implementation of add_stat_label(location = "row") has been updated. The function now merges columns "label" and "stat_label" instead of modifying the "label" column directly. This could be a breaking change if users had manually updated results, for example, from a tbl_regression() table to merge with tbl_summary() using tbl_merge()

• The function add_stat_label() no longer auto-switches location = "column" requests to "row" in the presence of "continuous2" variables.

gtsummary 1.3.7

• No changes. Resubmitting to resolve CRAN quirk.

gtsummary 1.3.6

New Functions

• Added function add_difference(), which adds difference between groups, confidence interval and p-value. (#617)

• Added function modify_caption() that includes table captions. For gt output, requires gt version > 0.2.2 (#701)

• Added function modify_table_body() allowing users to more easily make changes to gtsummary tables

• Added function remove_row_type() for removing header, reference, or missing rows from a gtsummary tables. (#678)

• Added selecting function all_stat_cols() that selects columns from tbl_summary/tbl_svysummary object with summary statistics (i.e. "stat_0", "stat_1", "stat_2", etc.).

• New selecting function was added all_tests() to make it easier to select variables based on the test used to calculate the p-value, e.g. add_p(test = c(age, marker) ~ "t.test", test.args = all_tests("t.test") ~ list(var.equal = TRUE))

• Added functions modify_column_hide() and modify_column_unhide() to hide and unhide columns in .$table_body. Simple wrappers for modify_table_header().

New Functionality

• Previously, the tbl_summary(digits=) only accepted integer values specifying the number of decimal places to round a statistic. The argument now accepts both integers or functions, e.g. digits = age ~ style_sigfig. (#708)

• The add_stat() function now supports tbl_svysummary() objects in addition to tbl_summary() (#688)

• The add_stat() function can now place statistics on the label row, or the level rows for categorical variables. (#714)

• inline_text.tbl_survfit() updated to allow users to select p-value (and other) columns. (#589)

Other Updates

• modify_header() has been updated so users may more easily access internal data while defining headers and so that it no longer adds its call to the gtsummary .$call_list (#719)

• The default value for include= argument for the add_global_p.tbl_regression() and add_global_p.tbl_uvregression() methods have been made the same with include = everything(), and the help files for these methods have been brought together in a single file. (#721)

• Introducing new package dependency {broom.helpers}

  • The tidying and preparation of tbl_regression() tables are now being performed by {broom.helpers} (#636, #607)

  • All select helper functions and the utility functions that make them possible, have been cleaned up and migrated to {broom.helpers}. (#648, #680)

  • Importing .generic_selector(), .select_to_varnames(), and .formula_list_to_named_list() from {broom.helpers}: this is a function that makes it easy to create selecting functions like all_continuous(). The internals allow for it to be used in {broom.helpers} and {gtsummary} seamlessly. (#680)

  • Theme element has been added for controlling the other tidy_plus_plus() arguments. (#692)

  • Variables that do not follow standard naming conventions are now parsed correctly and presented in the regression tables.

• The tbl_regression() function is now an S3 method. The new interface allows for special handling of different model types using S3 methods: tbl_regression.default(), tbl_regression.lmer(), tbl_regression.glmer(), tbl_regression.survreg()

• tbl_regression(add_estimate_to_reference_rows=) argument has been added. Also added to tbl_uvregression(). (#692)

• Theme element for tbl_regression(add_estimate_to_reference_rows=) has been added. (#677)

• Removed "Statistics presented:" and "Statistical tests performed:" prefixes from the tbl_summary() %>% add_p() footnotes.

• The codebase powering add_p() and related methods has been refactored for better performance, organization, and customizability. (#622)

  • For clarity, a help file listing each test available within gtsummary and the pseudo code for calculating the p-value has been added (see ?tests)

  • Each add_p() method now has the test.args= argument. Use this argument to pass additional arguments to the statistical method, e.g. add_p(test = c(age, marker) ~ "t.test", test.args = c(age, marker) ~ list(var.equal = TRUE))

  • Additional tests have been added: paired t-test, signed rank test, and more. See ?tests for full list.

  • More robust unit testing implemented for all add_p() methods.

• Added messaging to tbl_stack() to inform users that the attributes from the first table passed take precedent over the others'. (#699)

• In the modfiy_*() functions, if users did not select any columns, they encountered an error. Now, if no columns are selected, instructions are printed for how to correctly select columns in a gtsummary table. Moreover, if no columns are selected, the gtsummary object is now returned unaltered. (#699)

• The add_glance_source_note() function has been generalized so users may pass any glance function. Previously, broom::glance() was being used with no option to change it. (#699)

• The ... arguments have been added to as_gt(). These dots are subsequently passed to gt::gt(...). (#701)

• Multiple imputation models created with {mice}, and multinomial regression models created with {nnet} are now supported in tbl_regression() (#645)

• Updates to add_global_p.tbl_regression() allowing for variable names with spaces and special characters (#682)

• Added digits= argument to style_percent() (#690)

• Users may now choose which tbl_regression() columns to report with a theme element. they can choose among the "estimate", "std.error", "statistic", "ci", "conf.low", "conf.high" and "p.value" (#637)

• Allow users to include the reference value in tbl_regression() via a theme element

• Users may change the symbol with a reference row symbol with a theme element. (#628)

Bug Fixes

• Bug fix when a default statistic is set using themes for "continuous2" variables that has length larger than one

• Bug fix when missing/non-missing percentages requested in add_n.tbl_summary()

Breaking Changes

• The default test for 2-by-2 tables with expected cell counts has been updated from the chi-squared test with continuity correction to the original chi-squared test for add_p.tbl_summary() (#721)

• Experimental function add_p.tbl_survfit(test.args=) in addition to accepting the formula list notation, also accepted a single string naming a test that was interpreted as everything() ~ "test_name". The single string is no longer accepted, and users must use the formula notation.

• Removed theme element N_fun that was previously marked as questioning and likely to be removed from the package.

gtsummary 1.3.5

New Functionality

• New summary type continuous2 allows adding labelled statistic rows to tables in tbl_summary() and tbl_svysummary(). You can report several lines of statistics with this type. (#620)

  • The all_continuous() function now selects summary types continuous and continuous2 by default.
  • Added all_continuous2() function for selecting summary type continuous2 exclusively.
  • Added theme_gtsummary_continuous2() to make continuous2 the default summary type for all continuous variables.

• New function add_glance_source_note() adds the statistics returned in broom::glance() as a source note on a tbl_regression() (#434)

• Exporting the modify_table_header() function, which is an advanced-use function used to make modifications to the .$table_header object to update printing instructions for the gtsummary object.

• Added two custom tidiers for use in tbl_regression() and tbl_uvregression(). (#635)

  • tidy_standardize() returns standardized coefficients using the {effectsize} package
  • tidy_bootstrap() gives bootstrapped parameter estimates, calculated using the {parameters} package

Bug Fixes

• Bug fix where estimate_fun= and pvalue_fun= were not being passed to tbl_regression() in tbl_uvregression()

• There was an environments bug when evaluating the LHS of the formula inputs. In some complex situations, a stored character vector of column names could not properly evaluate (#604)

• Fixed style_ratio() bug where there were rounding errors near one (#651)

• Fixed style_sigfig() bug where there were rounding errors near thresholds (#638)

• Adding the footnote from the stat columns describing the statistics presented to the overall column (#643)

Other Updates

• Refresh of vignettes to use recently released functions (#649)

• Moved the nevent column to after the N column when add_nevent() is called on a tbl_regression() object (#439)

• gtsummary themes updates

  • Add theme_gtsummary_mean_sd() theme to report mean and SD by default and use t-tests and ANOVA in add_p() (#654)
  • Added first draft of the NEJM theme
  • Added the mid-point decimal separator for the Lancet theme

gtsummary 1.3.4

• Added a copy of tidyselect's where() function to allow users to use predicate select helpers (#632)

• Fixed tbl_cross() bug where function defaulted to 'column' when margin = NULL. Now it defaults to display no margins when NULL. (#624)

• Changed default of tbl_survfit() missing argument from '\U2014' (em dash) to NULL (CRAN issue). Em dash is still displayed by default in tables but it is set later in function.

gtsummary 1.3.3

New Functions

• The {flextable} has graduated from Experimental status! Introducing as_flex_table(), which replaces as_flextable(). The updated function includes improvements to the default aesthetics of the tables, and improved consistency for spanning header rows.

• Added tbl_svysummary() function to summarize complex and weighted survey designs. tbl_svysummary is now its own class that works with add_n(), add_p(), add_q(), add_stat_label(), add_overall(), inline_text(), tbl_merge() and tbl_stack() (#460).

• The family of tbl_survfit() functions has been greatly expanded!

  • tbl_survfit.survfit(), tbl_survfit.list(), and tbl_survfit.data.frame() have been added that accept a single survfit object, list of survfit objects, or a data frame for more flexible creation of univariate survival tables.
  • add_p.tbl_survfit(), add_n.tbl_survfit(), add_nevent.tbl_survfit() have been added to include additional information in tbl_survfit() tables.

• Adding as_hux_table() after the huxtable 5.0.0 release.

• Added show_header_names() function to assist when updating table headers, footnotes, and spanning headers. The function prints the current underlying column names along with their labels easing the process of identifying the column names needed to make updates. (#539)

• Added a language theme, theme_gtsummary_language() for translating tables into Spanish, French, Portuguese, German, Chinese (Traditional and Simplified), Hindi, Marathi, Gujarati, Japanese and Swedish (#511)

• Added style_number() function which allows for granular control of how numbers are formatted throughout the package. The style_percent(), style_pvalue(), style_sigfig(), and style_ratio() functions have been updated to use style_number() in the background. The implication is that users can now control how every number in a gtsummary table appears. For example, formatting can be updated to use the comma as the decimal mark and also specify the big mark using the gtsummary themes. (#458)

User-facing Updates

• Added support for competing risk cumulative incidence estimates to tbl_survfit() (#64, #448)

• Updated API for set_gtsummary_theme(). Users no longer need call set_gtsummary_theme(theme_gtsummary_journal()); rather, they call theme_gtsummary_journal(). Each built-in theme now has an argument set_theme = TRUE. When FALSE, the theme function will invisibly return the named list the theme elements, and the theme will not be set. (#522)

• Users can now specify how many decimal places to round statistics for categorical variables in tbl_summary(), e.g. 45 / 100 (45.0%). (#458)

• Added the 'The Lancet' theme to theme_gtsummary_journal()

• Updated the handling for arguments that accept functions to allow users to pass anonymous functions using the tidyverse shortcut notation, e.g. ~style_pvalue(.x, digits = 2).

• The header for the tbl_stack(group_header=) column is now integrated into a typical gtsummary framework, meaning that all standard functions can be executed on it, e.g. modify_header() for non-gt output.

• Added type= argument to add_global_p(), and added include= and keep= arguments to add_global_p.tbl_uvregression() (#554)

Internal Updates

• Updated add_n() internals to be more efficient without recalculating statistics previously saved in tbl_summary()

• {survival} package moved from Imports to Suggests

• The add_overall() function is now a method function, and add_overall.tbl_summary and add_overall.tbl_svysummary added (#460).

• Updated the variable labels for age and marker in the trial dataset.

• Removed large *.gif files out of the package to reduce build size (#485)

Bug Fixes

• Fixed bug where source note was not made smaller font size with compact theme when table was printed with {flextable} (#584)

• Bug fix for tbl_summary() when a data frame contained an ordered factor column (#567)

• Bug fix when only categorical summary statistics were requested for continuous variables in tbl_summary() and tbl_svysummary() (#528)

• Bug fix when named list of {gtsummary} objects is passed to tbl_merge(x=) (#541)

• Bug fix when for tbl_uvregression() when adjustment variables were included in formula = "{y} ~ {x} + age". The adjustment variables were being printed in the resulting table. (#555)

Breaking Changes

• All lifecycle::deprecate_warn() have been upgraded to lifecycle::deprecate_stop() for <= v1.2.0 (released Aug 2019)

• Removing as_flextable() and replacing with as_flex_table() due to a name conflict with flextable::as_flextable (#462)

gtsummary 1.3.2

• Now returning all columns from broom::tidy() in .$table_body() (#516)

• tbl_stack() now accepts a named list of gtsummary tables when using the group_header= argument (#524)

• add_p.tbl_summary() bug fix for Wilcoxon rank-sum p-value calculation introduced in the last release (#525)

• Delaying the release of as_huxtable() until the next {huxtable} release.

gtsummary 1.3.1

New Functions

• Introducing themes in {gtsummary}. Use the function set_gtsummary_theme() to set new themes, and review the themes vignette for details on setting and creating personalized themes. (#424)

• New functions modify_footnote() and modify_spanning_header() give users control over table footnotes and spanning headers. (#464)

• Introducing as_huxtable()! The function converts gtsummary objects to {huxtable} objects. {huxtable} supports indentation, footnotes, and spanning headers with Word, HTML, and PDF output. (#469)

• New function add_stat()! Add a new column of any statistic to a tbl_summary() table (#495)

User-facing Updates

• The following columns in tbl_summary() are now available to print for both continuous and categorical variables: total number of observations {N_obs}, number of missing observations {N_miss}, number of non-missing observations {N_nomiss}, proportion of missing observations {p_miss}, proportion of non-missing observations {p_nomiss}. (#473)

• Improved appearance of default as_flextable() output (#499)

• Added tbl_cross(margin=) argument to control which margins are shown in the output table. (#444)

• The missing values are now included in the calculation of p-values in tbl_cross().

• Messaging about statistical methods used has been added for add_global_p(), add_q(), and combine_terms(). (#471)

• Added include= argument to tbl_summary(). The preferred syntax for p-values with correlated data is now tbl_summary(..., include = -group_var) %>% add_p(group = group_var). The group variable is now no longer removed from the table summary. (#477)

• add_stat_label() function updated with location= and label= arguments to change the location of the statistic labels and to modify the text of the labels. location = "row" is now the default. (#467)

• tbl_stack() function added the group_header= argument that groups the stacked tables and adds a horizontal header row between them. (#468)

• Updated handling for interaction terms in tbl_regression(). Interaction terms may now be specified in the show_single_row= and label= arguments. (#451, #452)

Internal Updates

• Improved error messaging when invalid statistics are requested in tbl_summary(statistic=) (#502)

• All columns in as_tibble() are now styled and converted to character. Previously, styling was applied to most columns, but there were a few that relied on default printing for the type of underlying data. This was ok to rely on this default behavior for as_kable(), but with the introduction of as_flextable() we needed to style and format each column to character. Potential to break some code in edge cases. (#493)

• Handling of passed custom p-value functions in add_p.tbl_summary() has been improved with more careful handling of the environments from which the functions were passed. Other related updates were also made:

  • Users may pass their custom p-value function as a quoted string or bare.
  • The basic functions for calculating p-values, such as t.test() can now be passed directly e.g. test = age ~ t.test. We now perform a check match check for functions passed. If it is passed, we replace it with our internal version that returns the p-value and assigns the test name.
  • If a user passes a custom function, and it's not the proper form (i.e. a named list return object) AND the function returns a single numeric value, we assume that is the p-value and it's added to the gtsummary table.

• Updated the gtsummary core script, utils-gtsummary_core.R, to refer to all non-base R functions with the pkg:: prefix, so other packages that copy the file don't need to import the same functions as {gtsummary} in the NAMESPACE. Now they just need to depend on the same packages. (#454)

Bug Fixes

• Bug fix for inline_text.tbl_summary() when categorical variable contained levels with empty strings. There is still an issue if a user tries to select the empty string, however.

• Fixed bug where some variables in tbl_cross() defaulted to dichotomous instead of showing as categorical (#506)

• Bug fix when using a tbl_summary(by=) with missing observations in by= followed by add_overall()

• Bug fix where values ">0.9" were incorrectly made bold using bold_p(). (#489)

• Bug fix for as_flextable(). (#482)

  • Added a formatting function to all numeric columns to force conversion to character.
  • Spanning headers were being printed in alphabetical order! Update to preserve the ordering.

gtsummary 1.3.0

New Functions

• Introducing tbl_cross(), add_p.tbl_cross(), and inline_text.tbl_cross()! Easily construct cross tabulations of two variables.

• Introducing tbl_survfit() and inline_text.tbl_survfit()! These will eventually replace tbl_survival(), which will no longer be encouraged. The new functions follow the structural guidelines of a {gtsummary} object and can be merged and stacked with any other {gtsummary} object (#280)

• Introducing as_flextable()! The function converts gtsummary objects to {flextable} objects. {flextable} is a great option when using R markdown with Microsoft Word output. {flextable} supports indentation, footnotes, and spanning headers with Word, HTML, and PDF output.

• Introducing as_kable_extra()! The function converts gtsummary objects to {kableExtra} objects. {kableExtra} supports indentation, footnotes, and spanning headers with HTML and PDF output. (#394)

User-facing Updates

• Updated default print engine for {gtsummary} objects. {gt} is the default printer for the R console and R markdown documents with HTML output. PDF, RTF, and Word output default to using {kable} with a note referring users to a new vignette explaining why {gt} was not used. (#395, #396)

• Updated add_p() custom p-value description to NOT require double escape characters for quotation marks (#361)

• Created structure and enumerated list of unit tests each vetted model must pass, and added the tests (#383)

Internal Updates

• Each gtsummary object has an associated .$table_header. The code needed to print a table with either gt or kable was previously a mix of information stored in the table_header, and code manually added to the gt_calls or kable_calls object. Now, all the information needed to print a table is stored in table_header. This has the advantage that any updates to the printing will now require an update to table_header only, and we no longer need to update the tibble, kable and gt calls. (#412, #414)

• The {gt} package is now released on CRAN, and we've updated to depend on the CRAN version instead of the version on GitHub. This also resulted in significant updates throughout the documentation and code. For example, we no longer provide instructions for installing {gt}, or include internal checks if {gt} is installed. (#420)

• Several functions have been made general, and may now be applied to any {gtsummary}-like object. Functions updated are add_q(), bold_p(), sort_p(), tbl_merge(), tbl_stack(), bold_labels(), bold_levels(), italicize_labels(), and italicize_levels(). (#434, #429, #373)

• In tbl_regression() we previously printed the estimate, confidence interval, and p-value for all models. But some models don't have associated methods for calculating the p-value or the confidence intervals. In this update, we now print the p-value if tidy() returns a "p.value" column. Similarly, the confidence interval is printed if tidy() returns "conf.low" and "conf.high" columns. (#391, #404)

Bug Fixes

• Bug fix when data frame passed to tbl_summary() with a single column (#389)

• In tbl_summary() passing an ordered factor in the by= argument no longer causes as error. (#453)

gtsummary 1.2.6

• Bug fix for random effects regression model where coefficients were not exponentiated when requested. Using broom.mixed::tidy() rather than broom::tidy() resolved issue.

gtsummary 1.2.5

Documentation

• Updated documentation and README to improve readability, added more cross-linking across pages, added search terms to help users find our package, and added gif demonstrations (#340)

• README images now build differently for website vs GitHub markdown to accommodate different output formats

Breaking changes

• Removed deprecated fmt*_() and cols_label_summary() functions (#365)

• Functions tbl_summary_() and add_p_() have been deprecated because the by= and group= arguments now accept strings (#250)

Syntax

• Package-wide update allowing arguments that accept variable names to accept bare/symbol inputs, character inputs, stored character inputs, and tidyselect helpers. When passing a single variable, the vars() function wrapper is no longer required. (#250)

  tbl_summary(trial, label = age ~ "NEW LABEL"))
  tbl_summary(trial, label = "age" ~ "NEW LABEL"))
  tbl_summary(trial, label = c("age", "trt") ~ "NEW LABEL"))
  tbl_summary(trial, label = c(age, trt) ~ "NEW LABEL"))
  tbl_summary(trial, label = vars(age, trt) ~ "NEW LABEL"))
  tbl_summary(trial, label = vars(everything(), -age, -trt) ~ "NEW LABEL"))
  
  age_column = "age"
  tbl_summary(trial, label = age_column ~ "NEW LABEL"))
  tbl_summary(trial, label = vars(age_column) ~ "NEW LABEL")
  
  purrr::map(c("trt", "grade"), ~tbl_summary(trial, by = .x))

• Updated tbl_uvregression() to allow flexible tidyselect inputs and improved error messaging for arguments x and y (#249)

• After the input updates in #250, the exclude= argument appearing in add_p(), tbl_regression(), tbl_uvregression(), as_gt(), as_kable(), and as_tibble() was redundant. The exclude= argument is now deprecated. Use include= instead, with tidyselect syntax. (#331)

• Functions all_categorical(), all_dichotomous(), and all_continuous() may now be used in tbl_summary() argument type= (#256)

User-facing improvements

• New pattern= argument in inline_text.tbl_summary(). Previously, we could only grab the entire cell from a tbl_summary() with inline_text(), and now we can get any single statistic reported (#254)

• Improved messaging for users who use knitr::kable() to print gtsummary tables, and users who have not yet installed the {gt} package (#347)

• New function combine_terms() allows users to combine multiple independent variables in a regression model into a single line after tbl_regression(). The single line does not report regression coefficients, rather a single p-value from the anova() function. (#310)

• In the regression modeling functions tbl_regression() and tbl_uvregression(), the users are presented an informative error message when the tidier fails (e.g. broom::tidy()) alerting them to the location of the error so they may address the issue (#337, #338)

• For each release of gtsummary, we now can make reference to the version of gt our release coincides with. The commit SHA for gt is now saved in an object called gt_sha, and the version of gt can be installed with remotes::install_github("rstudio/gt", ref = gt_sha) (#329)

• Created "style" family of functions

• Improved error messaging in tidyselect_to_list() (#300)

Other features and fixes

• Updated class detection to use inherits(), and added secondary class of "gtsummary" to all objects. This allows users to create their own cobbled/custom gtsummary objects while utilizing the gtsummary print functions (#249)

• tbl_summary() will now summarize columns of class difftime (#343)

• Infrastructure update to the way styling/formatting functions are returned. Styling functions are now returned as a column in the .$table_header tibble. The update simplifies handling of these styling functions in tbl_merge() and tbl_stack(). (#298, #299)

• Bug fix for tbl_summary() when variables were all NA (#344)

• The data summary function add_p() now uses probabilities rather than counts to calculate expected cell counts to avoid an error when working with large data sets. (#341)

• Cubic spline terms are now accurately matched to a variable name/term (#312)

• Bug fix when non-standard evaluation arguments were passed in method.args= argument of tbl_uvregression() (#322)

• Updates after the gt package deprecated gt::cells_data() in favor of gt::cells_body(). Check added to as_gt() ensuring a version of gt with gt::cells_body() in its NAMESPACE

• Lowered minimum required version of R to v3.4 (#356)

• Removed {broom.mixed} dependency as the {broom} package contained all necessary tidiers (#354)

gtsummary 1.2.4

• Bug fix in as_kable() where column header did not match statistics presented when certain levels of the by= variable are entirely missing in tbl_summary() (#304)

• Updated the trial example data set "trt" variable to be "Drug A" and "Drug B" instead of "Placebo" and "Drug"

• Improved messaging to users when an error or warning occurs while calculating a p-value in add_p(). Also, p-values are no longer omitted from output when a warning is encountered during their calculation (#283)

• Added tidy_fun= argument to tbl_regression() and tbl_uvregression() allowing users to pass tidiers that are not in the {broom} and {broom.mixed} packages (#247)

gtsummary 1.2.3

• tbl_uvregression() now accepts an x= argument to build univariate regression models where the covariate x remains the same while models are built the with remaining variables as the outcome (#294)

• Internal updates to the way {gt} is installed during CRAN checks.

• Bug fix when stacking tbl_summary objects with calculated p-values.

gtsummary 1.2.2

New Features

• tbl_summary objects may be stacked and merged with tbl_stack() and tbl_merge() (#230, #255)

• The add_n() function now reports additional statistics: total N, non-missing N, missing N, and their percentages. The missing = argument has been deprecated in favor of the statistic = argument. (#237)

• Users may now pass a list of formulas, named lists, or a combination of both (#251)

• Users can add an option to their script to append any {gt} calls when a {gtsummary} object is printed: gtsummary.as_gt.addl_cmds

• Added include = and exclude = arguments to tbl_uvregression() (#240)

• Added standard evaluation variants, tbl_summary_() and add_p_() (#223)

• Added as_tibble() function that converts any {gtsummary} table to a tibble (#245)

• New show_single_row argument in tbl_regression() and tbl_uvregression() allows any binary variable to be printed on a single row. Previous argument show_yesno is now deprecated. (#220)

Documentation

• Added a gallery of tables possible by merging, stacking, and modifying {gtsummary} arguments (#258)

• Added a vignette documenting each global option that can be set in {gtsummary} (#289)

• Added {lifecycle} badges to mark deprecated and experimental functions (#225)

Other Updates

• The by = column in tbl_summary() now has missing variables dropped rather than halting with error (#279)

• Bug fix in vars() selection where only first variable listed was being selected (#259)

• Bug fix where logical variable labels printed as NA in tbl_regression() (#248)

• tbl_merge() now interprets tab_spanner = text with gt::md() (#253)

• No longer checking outcome variable name for consistency in tbl_regression()---only checking independent variable names (#287)

• Improved error messaging for add_global_p() (#243)

• Removed gt::cols_merge() function ahead of the {gt} package PR 355 that changes the cols_merge() API (#222)

• Updated API for using custom functions to calculate p-values in add_p(). User now may reference a custom function by its name. (#226)

• Removed legacy support for tidyr version less than 1.0.0 (#235)

gtsummary 1.2.1

• Vignettes no longer install the {gt} package (required for CRAN check) (#217)

• Added ability to name custom add_p() tests (#213)

gtsummary 1.2.0

• Users can pass variable names in backticks (#212)

• The group = argument in tbl_summary() has been moved to add_p() (#208)

• Users can now write custom functions to calculate p-values in add_p() (#194)

• In tbl_summary() the by = argument accepts a bare variable name instead of the variable name passed as a string (#193)

• Added support for column, row, and cell percentages in tbl_summary() (#181)

• Users can now set default p-value formatting functions, regression coefficient formatting functions, default level for confidence intervals, and formatting functions in tbl_survival() (#120)

• The {gt} package is no longer a required dependency. If {gt} is not installed, tables will be printed with knitr::kable(). The as_kable() function was added to the package as well. (#180)

• The function as_gt() now has include = and exclude = arguments

• Updated some function names to be the same as they were in the first version

    bold_p()            <-  tab_style_bold_p()

    bold_levels()       <-  tab_style_bold_levels()  
    italicize_labels()  <-  tab_style_italicize_labels()  
    italicize_levels()  <-  tab_style_italicize_levels()  

• Passing named lists in tbl_summary() is now defunct.

• tbl_stack() fix for tbl_uvregression objects (#175)

• Option to exclude some variables from testing when using add_p() (#164)

gtsummary 1.0.0

First release since major re-factoring. The {gt} package is now used as the print engine to create all tables. Some function names have been modified to be more in line with other {gt} function calls, and additional functions have been added. The API for some functions has also been updated. Review documentation and vignettes for details.
