That's a small file! Seriously, people work on datasets of 100Mb or so in 1Gb (or even 512Mb) machines. However, some care is needed to select a good way to read the data in (if read.table, do follow the advice on the help page), and it would probably be better to use a database interface (see the Data Import/Export manual). -- Brian D.
