titleBoosting RStudio and Shiny Server

You can boost RStudio and Shiny Server by opening the options page (using the options icon to the right of the open button). Your Researcher Desktop will remain in the boosted state for 31 days. It will then downsize. At any time during the last 7 days of the boosted window, you can request an additional 7 days by clicking the "Extend" button. The date and time of the scheduled downsize is displayed above the "Open" button on the Home page. Note: boosting and downsizing require the RStudio and Shiny Server to reboot and any running processes or file transfers will be terminated.

How do I upload my existing R Shiny web app to my RStudio and Shiny Server?

...

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

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