My institution recently installed GitLab for us. I\'ve figured out how to install R packages from the GitLab server using devtools::install_git and it works as
Per Ciro's comment, authenticating using
https://user:password@domain.com/user/repo.git
does the trick. So the complete call would be
devtools::install_git('https://user:password@mini-me2.lerner.ccf.org/nutterb/modeltable.git')
Please note that there may be security concerns with passing the user name and password this way. I'm not completely educated on those concerns. This works well enough for my purposes because I am authenticated on my company's network to even see the GitLab server.
