I want to upgrade R from 2.15.2 (stable) to 3.0.1 (active development). I want to do so because of a bug in the current version with plotting. I look at this page, but I don't know what to do with it.
I see that some good citizen has made his own PPA's for the new R. Should I use those? Or should I somehow make my system point to the active development version? I'd like to enter a couple of lines of code into a terminal and from then on have the update manager give me relevant updates. It seems like a volunteer PPA would be less dependable than whatever is coming down the pike with the next ubuntu version?
Anyway, what particular lines of code would I enter such that when I enter
sudo apt-get upgrade I get the new R?
