As stated here by RStudio Support:

Are you able to install packages in R?

If you're having issues, we recommend trying to install packages in R (outside of RStudio) and see if you're able to do that. If not, please check the possible solutions below.

Therefore, one needs to:

  • switch to Terminal.app,
  • while inside your Terminal, your R console must be started with the sudo privileges. Otherwise, it will yet again fail with a permission denied error. Hence, inside your Terminal, type sudo R,
  • and then install whatever package is necessary: e.g. install.packages("mlbench").
