RStudio
On the Yens, RStudio is available via JupyterHub. You can access your files and scripts and develop R code in a convenient environment.
Warning
RStudio only has a single version of R. Right now, it is version R/4.3.0.
Launch RStudio from JupyterHub Launcher interface:

RStudio will open up in a new tab.
Warning
RStudio may take some time to load during startup.

Danger
Do not install packages directly from RStudio on JupyterHub. Instead, use the terminal and run R to install packages. This ensures compatibility with the Yen cluster environment.
See this guide on how to install R packages on the Yens. Make sure the R module you load is the one RStudio is using.
