Memory capacity question for a specific situation

Hello!

I am trying to figure out if my latest R for 64 bits on a 64-bit
Windows 7 PC, RAM = 6 GB could read in a dataset with:

~64 million rows
~30 columns about half of which contain integers (between 1 and 3
digits) and half - numeric data (tens to thousands).

Or is it too much data?
And even if it could read it in - will there be any memory left to
conduct, for example, cluster analysis on that data set...


Thanks a lot!
