  1. For the new session, you can choose from the GNOME graphical user interface, the Unity graphical user interface, and xterm command line terminal. For most users, Unity is the best option. Command line access is available inside Unity via the built-in Terminal app.

One of the features of RStudio and Shiny Server is that the web access of the Shiny Server is pre-configured, so the end-user has one-click HTTPS access to the R Shiny web app (see above “Connecting “Connecting to the R Shiny Web App”App”). If you have an existing R Shiny web app that you would like to host on RStudio and Shiny Server, please follow the instructions below to upload your app.

  1. Verify that the R Studio and Shiny Server web app access is working, by visiting the Shiny site (see above “Connecting to the R Shiny Web App”). You should see the “Welcome to Shiny Server!” default Shiny demo app.

  2. Open RStudio Server (see above “Connecting via RStudio Server”).

  3. In the “Files” panel at the bottom right of RStudio, check that the current working folder is /srv/shiny-server. This is the default folder that Shiny uses to store web app files.

  1. The uploaded Shiny app will now be hosted on your RStudio and Shiny Server. You can verify this by visiting the Shiny site (see above “Connecting to the R Shiny Web App“). When you do so you should see your web app rather than the default welcome site.
