RStudio

RStudio is an integrated development environment (IDE) for R, a programming language for statistical computing and graphics. It is available in two formats:

• RStudio Desktop, a regular desktop application that most users are familiar with on their laptops, desktops or workstations.

• RStudio Server runs on a remote server and allows accessing RStudio using a web browser.

On Sol, RStudio Server is available through Open On Demand based HPC Portal.

Available Versions

The following R versions are supported on RStudio

• R 3.5.3

• R 3.6.3

• R 4.0.2

• R 4.0.3

• R 4.1.2

Usage

• Login to the HPC Portal

• Click the Interactive Apps dropdown and select RStudio Server

• Choose the version of R, resources required to run your job, and click the submit button

• When resources are available, OOD will launch RStudio Server on the compute node. This may take a few minutes.

• Click the Connect to RStudio Server button, to launch RStudio in a new browser tab.

• When you are done, click File>Quit Session to close your session.

  • You will be provided an option to save or discard changes to the .RData file

List of R Packages

Running a server requires a daemon to be always running consuming resources that could be used for running simulations. RStudio Server and the underlying R packages are bundled together in a singularity container. Requests for adding or removing R packages will only be accepted when new versions of R/RStudio are made available. 

Need access to these packages outside RStudio?

If you need to use these packages in a batch R program rather than RStudio, then you need to run R from the singularity container. Add the following two lines to your submit script to modify your MODULEPATH variable (assuming R 4.02. base module)
