Developers

Dependencies

It is highly recommended that you use the RStudio IDE to develop this package. In addition to an R installation, you’ll also need to install Rtools and a TeX distribution. TeX Live is a comprehensive distribution that seems to work well.

Once you have cloned this repository, you’ll need to download the build package dependencies. These dependencies are managed with packrat and can be restored by running

if (!require(packrat)) install.packages("packrat")
packrat::on()
packrat::restore()

Documentation

The roxygen2 R package is used to manage KeyboardSimulator’s documentation. Do not edit any of the files that have a warning comment at the top about manually editing those files!

You can regenerate package documentation with the RStudio shortcut Ctrl+Shift+Enter, or by running

roxygen2::roxygenize()

The project is set up to do this whenever building and testing the package.
