INSTALL R STUDIO ON CONDA INSTALL

If you encounter difficulties while trying to install a common R package then try this: You do not need to load any modules to install sf, rgdal, geojsonio or terra. You never need to load the rh/devtoolset/8 module on della8 since the default version of GCC is sufficient. To install some packages (e.g., ncdf4) you will need to load certain environment modules ( see below). Once you have installed the packages on della8, make a new OnDemand RStudio session and the packages will be available. # cancel all running OnDemand RStudio sessions The commands below can be used to delete the old packages of version 4.1 and then install a new one: The default version of R on the updated nodes is 4.1. To see which versions you have used, run the following command: $ ssh on della8, remove any previous package installations for the version of R that you plan to use. You can get to della8 from the OnDemand main menu by choosing 'Clusters' and then 'Della Cluster Shell Access.' You can also connect via SSH: You cannot install the packages using OnDemand RStudio. The solution is to remove all your packages and reinstall them on the della8 login node.

If you are encountering problems with packages suddenly not working then it is most likely because your jobs are now running on the upgraded nodes as opposed to the old SDL 7 nodes. The Della operating system upgrade from SDL 7 to 8 is now essentially complete.
