Hi Peter, I share your experience with trying to help IT departments setting things up. The network directory of the students is mapped to a drive, but R still uses the unc path instead of the drive when attempting to create that user library. Unless I do it manually of course. The only solution I see right now is to set the HOME or R_LIBS_USER environment variable in Renviron, but that should be done each time a new student logs into the computer. Or is there a way to ensure R uses the mapped drive instead of the network unc path, either using an R setting or by messing with Windows itself?
