Simple question (I think) but have not found anything. I want to add package in R like GGPLOT2 and use it in IDE/command line for sage (not note book). I am using Ubuntu Lucid and have r working on its own.
Is it better to use the R in the Sage folder and add packages to that folder? If so how, as in Ubuntu everything goes to the main R installation.
Or is there an easy way to just point RPy to the main R installation when using SAGE.
