Writing R packages

Introduction

Notes from the R Packages book.

The Big Picture

From The Whole Game chapter.

  • Use the devtools package, which contains a set of packages that support package development.
  • Use create_package() to initialise a new package.
  • Use use_r(function_name) to create and/or open a script in R/.
  • Use document() to build the documentation.
  • Use load_all() to load all functions in R/; load_all() simulates the process of building, installing, and attaching.
  • Use check() to check that everything is working.
  • Use install() to install your package.
  • Use use_git() to make a Git repository.
  • Use use_github() to connect to GitHub.
  • Use use_readme_rmd() to create a template README.Rmd file then use build_readme() to render README.md.
