I have tried to move from SAS to R a few times at this point it's largely inertia there is so much in my org already written in SAS makes it very difficult to convince people to change.

I do like the SAS dev tools (especially Enterprise Guide). I'd really love if R had some sort of GUI front end for non technical people. Eg. I know the finance analysts in our org wouldn't have a clue how to configure their own ODBC sources -which you need to do with R Studio until it's as easy for them as SAS convincing them to switch won't get any traction.
