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. The Della operating system upgrade from Springdale Linux 7 to 8 is now complete. If you attempt to install R packages from within RStudio you will encounter this error: > install.packages('microbenchmark') Keep in mind that the visualization nodes are shared between all users. If your work happens to require internet access in RStudio then use one of the visualization nodes by choosing 'Interactive Apps' in the OnDemand main menu and then either 'RStudio Server on Della Vis1' or 'RStudio Server on Della Vis2'. Previously, it was possible to install R packages and carry out other network operations in RStudio but this is no longer the case. The correct way to install R packages is to do so on the command line (see Installing R Packages below) before starting a session. Internet access has been disabled in RStudio sessions due to security and compliance reasons.
