R help - Apr 2010 - vector matching

Hello all,

I have searched the archives for a similar problem to no avail.  I
could use  your help.

I have a bunch of vectors organized into two matrices, x and y.  These
vectors (as rows) consist of combinations of elements such that order
does not matter.

I want to create a third matrix from the first two, which is basically
all the rows in x and all the rows in y, excluding the rows that they
both have in common.

%in% seems to match individual elements, not entire rows, so something
else is needed.

Any help is appreciated.

Thanks,

-Michael

If I understand:

unique(t(apply(rbind(x, y), 1, sort)))
