回答1:
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, - however, R console must be started with the sudo privileges(otherwise, it will yet again fail with a perission denied error):
sudo R, - and then install whatever package is necessary:
install.packages("mlbench").
