[R] Data File Size Problem

[Prof Brian Ripley]

By at least some definitions, a `large file' is one over 2Gb, so yours is 
hardly `huge'.

I don't know what .dat format is (or, rather, I know many different 
definitions of it).  But your problem seems a small one 
for the current limits of 32-bit R for Windows, and on more capable 
platforms (e.g. 64-bit Unix or Linux) a tiny one.  Just make sure you have 
lots of RAM in your computer: R can make use of up to 3Gb (and the OS will 
want some, too).
