There's actually Jupyter. Then there's a julia backend for ess as well.

I'm using R regularly, and I couldn't care less for R-Studio. In our stat group, only 1 statistician out of 7 is using R-studio, while all of them are using R.

The IDE has very little to do with adoption.

There can be a difference between IDE choice among professionals and the role of an IDE in introducing people to the ecosystem. On ramps don't start at the target elevation.

For what I see, the first and foremost initiating factor for a statistical package is education, and second it's available methods/packages. You have universities where you can clearly see that the predominant taught package is Stata, or R (and in the latter, the choice of UI is mostly arbitrary).

In the end though, unless you want to reimplement methods, you can count on having R packages for any method you can think of.

Few statisticians though spend the time to evaluate different IDEs than what they where taught. I've "converted" many still using Rwin.
