Details

System requirements for packages are provided through RStudio Package Manager via the pak package. The install commands provided from pak are added as `RUN` directives within the `Dockerfile`.

The R version is taken from the `renv.lock` file. Packages are installed using `renv::restore()` which ensures that the proper package version and source is used when installed.
