Usually the problem is that people do not know how to do that in the
Windows versions. The easiest way (and the only easy way on NT4 with
rw0630) is to set up a shortcut to R.exe on the desktop or on the start
menu, and put

path\to\bin\R.exe --vsize 10

as the target.  As I find both the default heap and the default cons cells
too small, I have my shortcut with 

--vsize 6 --nsize 250000

That makes the process take about 14Mb, and on a 32Mb machine that
is about as much as is comfortable without paging.

Yes, we have made that point to him via the list before. Could Peter
Mandeville please use a signature?
