Load the module you need for your packages to run, if no additional modules are needed, leave it blank.
Each user can only start one OnDemand RStudio session on one compute node at a time. If you need to start multiple RStudio sessions, please make sure you select a different nodename from your current running session.
Click “Launch” and wait for available resources
Once it’s ready, click on the Connect to RStudio button
When you finished, exit RStudio properly q(), then close the RStudio tab, and go back to the main page click Delete to end the session

Debug OnDemand RStudio Pax#

Logs from RStudio could be crupted sometimes which will cause RStudio not launching from OnDemand. Here are a few things you can try. Make sure all RStudio sessions are deleted before this.

Rename the file /cluster/home/$USER/.local/share/rstudio

$ `mv /cluster/home/$USER/.local/share/rstudio /cluster/home/$USER/.local/share/rstudio_bkp`
Rename the /cluster/home/$USER/.RData

$ `mv /cluster/home/$USER/.RData /cluster/home/$USER/.RData_bkp`

Now you can try relaunch RStudio. If it’s working properly for you, test out your workflow.

If you get all you need without issues, you can go ahead and delete /cluster/home/$USER/.local/share/rstudio_bkp and /cluster/home/$USER/.RData_bkp
