repo2docker automatically picks up if there is a *.jats.xml file in a repository which has code chunks with language "r" and then installs and configures the required software (stencila R package, nbstencilaproxy).
You can also add a runtime.txt file and or an install.R file as defined in the repo2docker docs.
