I attempted to make a new default stan document which would open whenever I opened a new stan file in RStudio. I followed the directions at RStudio User Guide - Custom Settings (for a Mac). Specifically, I added a file "default.stan" to the terminal directory in the Mac directory path (I think I had to create this directory myself).
The new default did not work. The original default document always opened. So to start with, the help page could use updating.
On a whim, I looked "inside" the RStudio application to search for where its default stan document is. Using "Show Package Contents" from the right-click menu, I found this document at "Contents/Resources/app/resources/templates/stan.stan".
Based on that filename, I then changed the name of my original file to "stan.stan". This worked!
There are many other files in the internal RStudio directory, those mentioned on the help page but also many others of different language types. I encourage folks to try this same trick if they also find the help page advice ineffective.
I do not know where the equivalent default directory is in Windows, but I suspect the same trick would apply. I also encourage an update to the help page.
