Configuring RStudio User Profile to load specific R version and libraries

[KevinMcDee]

I'm running RStudio IDE in Chrome on a HPC (ie. a unix cluster) and I want to configure my user profile to automatically launch a particular R version (including the correct libraries) when I login. Which files need to be configured to achieve this goal? The HPC admins aren't much help.

RStudio IDE in Chrome on a HPC

I'm not sure if it's RStudio Desktop run with OpenOnDemand or something similar? Not RStudio Server?

Have you already seen this page? I expect it would work to add a line like

export RSTUDIO_WHICH_R=/usr/bin/R

in your startup file, typically ~/.bashrc

The exact path to the right version might be more tricky to find. In my case, I have to first load an R module to find those paths:

$ module load R
$ which R
/mypath/apps/hpc/software/R/4.2.0-foss-2020b/bin/R
$ ls /mypath/apps/hpc/software/R/
3.2.3-foss-2016b  3.3.3-foss-2016a  3.4.1-foss-2016b      3.5.0-foss-2016b-avx2  3.6.1-foss-2018b  4.1.0-foss-2020b
3.2.4-foss-2016b  3.3.3-foss-2016b  3.4.2-foss-2016b-fh2  3.5.1-foss-2018b       4.0.3-foss-2020b  4.2.0-foss-2020b
