[R] matrix comparison, and cbind issues.

Mark,

	A and B will probably be different sizes. Won't 'C<-A-B' just do the
subtraction of matrix A by matrix B? 
So What I was thinking was that it would find 2 numbers one at position 6
and the other at position 9. If it finds roughtly these numbers in matrix B
then it will identify this and remove that row from matrix A.

If A and B are the same size ( I can't tell ),then you can C<-A-B to get
the dfiference but that might
Be simplifying things too much.

If it isn't simplifying thigns too, then let me know and I think I can
show you how to do the rest.
If it is, then my bad and I apologize.
