RStudio troubleshooting

If you have trouble running RStudio, installed by one user launched from another user on the same machine. Your permissions and ownership might be broken. Try first to re-install RStudio. If this doesn't work the run:

sudo chown -R root RStudio.app
sudo chmod -R 0755 RStudio.app

As a note, this worked for me after being failed by the data.table instructions.
