R devel - Feb 2018 - [R-win] Bug 17159 - recursive dir.create() fails on windows shares due to permissions (MMaechler: Resending to R-windows@R-pr..)

I can easily believe that. It was maily for Joris, that it might not be
necessary to reinstall.

using symbolic links to the network share created within the temporary folder,
but would much prefer that R support UNC paths ? it seems a reasonably simple
fix.

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?

Cheers
Joris
