By default the RStudio server will use the base conda environment for the R library and R version. If you need other packages or a different R version you should create a conda environment containing all the packages and appropriate R version on the login node. You then would give the full conda environment path (i.e. /home/username/.conda/envs/my_env) in the "conda env fullpath" box to specify the location of the conda environment to get your desired R packages and version. For more information about creating conda packages on the HPC please refer to the appropriate documentation: https://hpc.uams.edu/display/HPC/Conda+and+Jupyter+App+Documentation |

You must leave the session and update your conda environment and resubmit the RStudio job to add packages that you have forgotten. |
