R-beta: Memory requirement in Win NT

I generally use S+ but have been dismayed by it's slow operation and memory hogging.  I recently downloaded R and was hoping my memory problems were over.  To the contrary, R seems to run out of memory almost immediately; particularly during read.table().

I tried to change the arguments on startup of R, for example:

	R -n200000 -v20

However, I get an error:

	The instruction at "0x0008001f" referenced memory at "0x0008001f".  The memory could not be "read"

I get this error regardless of the values I use for -n or -v and I get the error if I try to use either the -n OR the -v arguments.

What gives?  It's enough to make me switch to SAS or (God forbid!) begin longing for a Microsoft product.

I have a Pentium 166 with 64 Megs of RAM and I'm running Windows NT.  Surely this is enough computational power if only I could tell R to use more resources than it starts with as default?  I would rather not go through the hassle of breaking down a read.table() command into a bunch of scan() commands or break up my dataset into multiple files.  I can load the same dataset with read.table() using S+ on this machine, it just takes forever.

I certainly appreciate any help.  Please respond to jmortz at snake1.cr.usgs.gov as well as the mailing list.

Thanks in advance for the advice.
