[R] Matrix Multiplication

[Paul, David A]

R1.7.1/Win2k:

Apologies if this posts twice - the first message
was not in plain text.

I have looked in help.start() and tried typing
"crossprod" and "%*%" into the RGui to get an idea 
for what R is using as internal algorithms for 
its matrix computations/manipulations... to no 
avail.

Could someone point me in the direction of some
documentation?  All I get for "crossprod" is

	function (x, y = NULL) 
	.Internal(crossprod(x, y))
	<environment: namespace:base>

Much thanks in advance,
	david paul
