As mentioned in Enable automatic commenting in Sublime Text for a custom syntax, .tmPreferences files are used to specify what the comment markers are for a syntax.

To edit the comment markers for R:

1. Install PackageResourceViewer
2. Open the command palette
3. Type PRV: O
4. Select PackageResourceViewer: Open Resource
5. Select R
6. Select Comments.tmPreferences
7. Edit the TM_COMMENT_START value to #' as desired
8. Save the file
9. Use the toggle comment functionality on an R file and see that it now uses #' instead of #
