2  System setup

You should use the latest version of R (currently 4.2.0) and a recent version of RStudio. It is a good idea to have git installed and have a GitHub (or similar) account.

You will also need to install the devtools package


This will also install the usethis, roxygen2 and testthat packages that we will use.

If you are using Windows, you may need to install Rtools if your package will contain C++ code or similar. You can download and install Rtools from https://cran.r-project.org/bin/windows/Rtools/ using the defaults. Rtools is not an R package.
