There is Rkward[1], available from the repositories in many linux distributions.

Discovered it recently, because I'm currently learning R, and few linux distributions outside the Mandriva family offer Rstudio straight from the repositories, and I'm lazy to download and do a manual install every time.

For many years, Emacs plus ESS was the standard workflow for R users. Vim users have their own plugin. On Windows, Tinn-R was impressive, and last I checked it was still going. Of course there is also Jupyter, PyCharm, and Eclipse, plus every text editor has support for R. If something were to happen to RStudio, there would be many fine alternatives for R.
