4.1 Restarting RStudio Session

4.1.1 Within RStudio

Session > Restart R (Ctrl + Shift + F10)

4.1.2 From the terminal

When RStudio locks up and you need to restart it. Note you will need to be on the VPN if you are not on the VT wireless.

1. Open a terminal
2. ssh into lightfoot: ssh pid@lightfoot.vbi.vt.edu
3. Look for your rstudio process by runing: ps aux | grep <YOUR PID> | grep rstudio

> ps aux | grep chend | grep rstudio
chend    163630  0.3  0.0 743120 100936 ?       Sl   09:51   0:04 /usr/lib/rstudio-server/bin/rsession -u chend --launcher-token 59FDC2A5
chend    182064  0.0  0.0 112708   968 pts/0    S+   10:14   0:00 grep --color=auto rstudio

4. Note which process rstudio is running on by looking at the 2nd column in the output (next to your pid), in this example the process number is 163630
5. Stop the process: kill -9 <Process number here>
