R package with private github dependency

Question

I'm developing an internal R package which is going to be stored and installed from github, but it depends on another R package which is also in a private repo.

I know how to specify remote dependencies with the devtools Remotes: tag (vignette) and I know how to install private repositories using install_github(source, PAT). But how do I do both? The idea is to have a server just install the package, and also install all of the dependencies on github.

Answer 1

Just putting @jeroen's response in answer format:

Store the PAT in an environment variable Sys.setenv(GITHUB_PAT = PAT) then devtools/remotes will automatically use it everywhere.

This works when the private repos all use the same PAT. I wonder how we'd do this for remotes with different PATs...
