Install dependencies

• If you have downloaded/forked this repository you can install the R dependencies with (assuming your working directory is at the top level of the repo):

  # install.packages("devtools") # uncomment if devtools not installed
  devtools::install_dev_deps()

• You can install the Stata dependencies, in Stata, with

  do depdendency

• For the pdf book please install the Fira Code font on your system from here

Building the book

• If you need to install LaTeX, in R install the tinytex package (which is included in the dependencies) and run

  tinytex::install_tinytex()

• Render all formats

  rmarkdown::render_site(encoding = 'UTF-8')

• Render the PDF book

  rmarkdown::render_site(output_format = 'bookdown::pdf_book', encoding = 'UTF-8')

• Render the HTML book

  rmarkdown::render_site(output_format = 'bookdown::gitbook_book', encoding = 'UTF-8')

• Render the EPUB book

  rmarkdown::render_site(output_format = 'bookdown::epub_book', encoding = 'UTF-8')

• Preview a specific chapter

  bookdown::preview_chapter("chapter-filename.Rmd")

• To build the chapters containing Stata code:

  • You need Stata installed on your machine.

  • You need to install Doug Hemken's Statamarkdown package, which is now on CRAN and is installed when you run devtools::install_dev_deps(), or install with

    install.packages("Statamarkdown")

  • If your version of Stata is installed at a default installation location the Statamarkdown package will find it. If your version of Stata is installed at a bespoke file path you'll need to set the file path to with something like

    library(Statamarkdown)
    stataexe <- "C:/Program Files/Stata17/StataSE-64.exe"
    knitr::opts_chunk$set(engine.path = list(stata = stataexe))

  • Install the Stata dependencies, in Stata, with:

    do dependency
