gtools R package

Project Status: Active - The project has reached a stable, usable state and is being actively developed. R-CMD-check CRAN RStudio mirror downloads

The gtools R package provides functions to assist in R programming, including:

  • assist in developing, updating, and maintaining R and R packages (ask, checkRVersion, getDependencies, keywords, scat),
  • calculate the logit and inverse logit transformations (logit, inv.logit),
  • test if a value is missing, empty or contains only NA and NULL values (invalid),
  • manipulate R’s .Last function (addLast),
  • define macros (defmacro),
  • detect odd and even integers (odd, even),
  • convert strings containing non-ASCII characters (like single quotes) to plain ASCII (ASCIIfy),
  • perform a binary search (binsearch),
  • sort strings containing both numeric and character components (mixedsort),
  • create a factor variable from the quantiles of a continuous variable (quantcut),
  • enumerate permutations and combinations (combinations, permutations),
  • calculate and convert between fold-change and log-ratio (foldchange, logratio2foldchange, foldchange2logratio),
  • calculate probabilities and generate random numbers from Dirichlet distributions (rdirichlet, ddirichlet),
  • apply a function over adjacent subsets of a vector (running),
  • modify the TCP_NODELAY (de-Nagle) flag for socket objects,
  • efficient rbind of data frames, even if the column names dont match (smartbind`),
  • generate significance stars from p-values (stars.pval),
  • convert characters to/from ASCII codes (asc, chr),
  • convert character vector to ASCII representation (ASCIIfy).
  • apply title capitalization rules to a character vector (capwords)
