6  Checking

• Use R CMD check/devtools::check()/Check button in RStudio Build pane

• Aim for 0 errors and 0 warnings - this is the minimum requirement for CRAN

  

• You can setup a GitHub Action to run this on every commit into repo

• usethis::use_github_action()/usethis::use_tidy_github_actions() or copy from https://github.com/r-lib/actions

• Stata and python have no such similarly thorough checking system, so well worth using

• Think about including tests with testthat or another testing package

• If your package passes R CMD check then you can build a pkgdown website for your package with one command pkgdown::build_site()

• Use win-builder for a further check https://win-builder.r-project.org/

  

• For both win-builder and CRAN you will need to submit the source version of your package as a .tar.gz file, e.g. in RStudio or issue R CMD build mynewpackage at the command line

  • Note the .tar.gz file is what remotes::install_github() makes then installs if installing from GitHub
