Shiny servers

Users of the Esrum cluster have two options for running Shiny servers: Either via a publicly accessible server for non-GDPR project/non-confidential data or by running Shiny directly or through RStudio on data in access-controlled projects.

The public Shiny server

Warning

DO NOT put any GDPR projected or otherwise confidential data in your SUN-CBMR-shinyapp sub-folders, as these folders are publicly accessible. Files and folders in SUN-CBMR-shinyapp are additionally writable by all users with the access to the folder.

UCPH-IT makes a public Shiny server available at https://shinyapp01.ku.dk/cbmr/. This server is accessible to everyone inside and outside UCPH. To make use of this service, you must first apply for access to the N-SUN-CBMR-shinyapp-R and the N-SUN-CBMR-shinyapp-W as described on the Applying for access page.

Once you have been given access to these groups, you can access the SUN-CBMR-shinyapp at ~/ucph/ndir/SUN-CBMR-shinyapp/. If you cannot access the ndir folder, then please see the Troubleshooting section on the Connecting to the cluster page.

It is strongly recommended that you create a folder with your username:

$ mkdir -p ~/ucph/ndir/SUN-CBMR-shinyapp/$USER

This creates a folder with your username and adds a shortcut to your home folder named shiny. To verify that everything is working correctly, create a file name app.R in ~/ucph/ndir/SUN-CBMR-shinyapp/$USER with the following content:

library(shiny)

# Define UI ----
ui <- fluidPage(
titlePanel("Hello, world!"),
)

# Define server logic ----
server <- function(input, output) {

}

# Run the app ----
shinyApp(ui = ui, server = server)

Then visit https://shinyapp01.ku.dk/cbmr/ and click on the folder corresponding to your username, and you should see the following in your browser:
