I am trying to use multiple versions of R in Shiny Pro by modifying r_path in the application's .shiny_app.conf file and it doesn't appear to be working.
I added the following to the server conf:
allow_app_override true;
And this is the entire .shiny_app.conf:
r_path "/home/dev/R-3.4.3/bin/R";
Is there something I'm missing here?
