We need more details about your problem to provide any useful 
help.  Are all the variables numeric?  Are they all completely 
different?  Is it possible to use `colClasses'?

Also, having "a couple of gigabytes of RAM" is not necessarily 
useful if you're on a 32-bit OS since the total process size is 
usually limited to be less than ~3GB.

Believe it or not, complaints like these are not that common. 
1998 was a long time ago!
