Review of RStudio (new IDE for R)

IDE announcement generated enthusiasm on HN a few days ago: http://news.ycombinator.com/item?id=2271511

Isn't R GPLv2? Isn't that incompatible with AGPLv3?

I don't know anything about the details, but apparently it's mostly GPLv2 or later: https://svn.r-project.org/R/trunk/doc/COPYRIGHTS

Well, I'll be. That certainly paints a different picture than what's stated in http://www.r-project.org/Licenses/

Thanks!

Since R isn't included in RStudio, merely acting as an interface with the R session, I doubt this is an issue at all.

RStudio has server and client components (rdesktop and rsession) and at least on the linux version rsession is dynamically linked to libR.so. R has historically been very lax about policing their binary API's for license violations, though.

This is confusing because R-Studio (with a hyphen) is also a file recovery utility...
