Start with FAQ 7.28 , http://cran.r-project.org/doc/FAQ/R-FAQ.html#Why-is-read_002etable_0028_0029-so-inefficient_003f However, I think you're going to have much bigger problems if you have a 3.1G data set and a total of 3.2G of RAM: what do you expect to be able to do with this data set once you've read it in? Have you considered storing it in a database and accessing just the bits you need at any one time?
