That solution works fine for the use case where each user has a network based home directory and needs to run R from there, but doesn?t help with my situation. I need to be able to support arbitrary network based paths in arbitrary numbers ? so mapping drives isn?t an option. I have found a workaround using symbolic links to the network share created within the temporary folder, but would much

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

Bug 17159 has been fixed (in R-devel), but there may be more issues left with UNC paths.

...the capacity of R . Can you tell me how much lignes and colones can R manipulates? Can I work with a data of 2 milions lignes? When I asked M.Maechler , he advices me to ask you about this.

I usually draw a complete blank if I try to assist our IT department with such issues (we really need better documentation than the Admin manual for large-system installs by non-experts in R). However, it is my impression that there are also options involving environment variables and LFS naming. E.g., map the networked user directory to, say, a P: "drive" and make sure that the

I can easily believe that. It was maily for Joris, that it might not be necessary to reinstall. -pd > On 17 Jan 2018, at 11:55 , Thompson, Pete <Pete.Thompson at iqvia.com> wrote: > > That solution works fine for the use case where each user has a network based home directory and needs to run R from there, but doesn?t help with my situation.

...) Currently needs the R-forge version of Matrix, version 1.2-8. A bit less than an hour ago, I have updated the gist with an updated proposal ifelse2() {and the current alternatives that I know}, modified so it *does* keep more, e.g. dim() attributes in reasonable cases. https://gist.github.com/mmaechler/9cfc3219c4b89649313bfe6853d87894#file-ifelse-def-r-L168 Hence my ifelse2() became even a bit longer (but not slower) working for even more classes of "yes" and "no". > On ifelse-checks.R: > * In function 'chkIfelse', if the fourth function argument name...

G'day all, I have daily scripts running to install the patched version of the current R version and the development version of R on my linux box (Ubuntu 18.04.4 LTS). The last development version that was successfully compiled and installed was "R Under development (unstable) (2020-01-25 r77715)" on 27 January. Since then the script always fails as a regression test seems to fail.
