Chapter 9 Package checks

Now that we’ve built an R package, we need to check it.

Run R check often to make sure you aren’t breaking something in your package.

9.1 RStudio

Keyboard shortchuts: shift + command + E (shift + ctrl + E)

OR use buttons

9.2 command line

from your shell

Rscript -e 'devtools::check()'

OR from within R

devtools::check()

OR with the newer package rcmdcheck

rcmdcheck::rcmdcheck()

9.3 the really hard way

R CMD BUILD your_package_folder
R CMD CHECK your_package_name.tar.gz
