But with a 32bit operating system, 4G is all the memory that can be
addressed (including the operating system). So your chances of
getting all the data into R seem very slim.

That might involve using a database which you can query from R, or you
might be able to use a Perl script to select what you require. I have
heard of people using Perl with Windows.
Someone once asked me to plot some SAS output which was several
hundred Mb. In that case, a simple Perl script cut it down to 3 Mb.
You might be lucky too.
Good luck.
