I have a shiny app deployed on www.shinyapps.io. The app includes a data set and one script (app.R).
All of a sudden I lost all the access to the data and the script on my local machine. Is there a way that I can download the script app.R and the data from www.shinyapps.io?
Yes, if you login to shinyapps and click on the app name in the dashboard, you should see "Bundle - Download" in the Overview. This will download a tar file which you can uncompress. It should contain app.R plus the other files required to make the app run at shinyapps.
