FWIW I am very good and close friends with the RStudio founders and several of their engineers. But most (power R) users I know (myself included) happily use their dailies from http://www.rstudio.org/download/daily/
It would be a lot of work to get (and keep) this packaged as RStudio found over the years to often require newer-than-packaged tools like Qt, Boost, and more. While it would be nice to see it packaged, maybe we have other more urgent tasks. Not sure. Good luck anyway! Dirk -- http://dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org
