# Using RStudio

RStudio is an IDE for R that can be run on Oscar.

## Launching RStudio

## Known Issues

Plotting figures may not work within RStudio. If this is the case, save the plots to a file, and view them through the Open On Demand Desktop App. If plots are required for your task, launch RStudio through the Desktop App.
