Can't Install R Packages in Sage
I'm running Sage 5.8 on Ubuntu 12.10 and am trying to install some R packages within Sage. However, when I enter
I get a green line and nothing happens. I am not asked what repository I'd like to use; when I specified a repository, I still got a green line and nothing happened. If I leave out the package name, I get a pop-up asking what package I want to install but nothing after that. What should I do?
