I got a Shiny Server running on an Ubuntu image on my RPi. Image (8GB) is available here: https://github.com/trestletech/RpiR#images . Although I work for RStudio, it is certainly not an officially supported architecture / environment.
It will not be placed in the RpiR package, which is the R interface in the WiringPi library, which allows digital-to-analog reading and writing to GPIO Rpi pins.
Unfortunately, I did not document the installation process very well, so I do not have much guidance for you at startup. There are some known issues on Shiny Server with Debian in general (you donβt want this to be officially unsupported), so Ubuntu will probably be an easier starting point, but there were a few other hacks that I had to take with me, unfortunately, did not record.
If there is enough interest, I can try to recreate the steps in a more reproducible way so that you can use more than just one image.
