Renv

To users

We use an renv enabled RStudio project to manage the local environment with libraries in order to ensure reproducible results, correct working directories etc. You can use the included one or create your own.
When you pull this repository, make sure to restart your R session (this is done automatically if you open this as an RStudio project). R will read the project specific .Rprofile file and thereby activate renv.
You can also activate it manually by using renv::activate(). This might lead to the download of many (potentially older) packages.
Keep in mind that you will be working in this specific environment as long as you're not switching to another project or manually deactivate renv (renv::deactivate()).

To contributors

If a new package is required, use renv::install("new package"). For updates, use renv::update("update_package").
Then add this to the lock file by running renv::snapshot() and commit the changes in renv.lock. A good overview can be found here
