I am sure someone can come up with a clever way of doing what I want---I
don't seem to be able to.
I want to check if a pair of numbers occurs as one of the rows of an n
by 2 matrix. If I was only checking whether a single number was in a
vector of numbers I would use %in% but I can't see how to generalize to
this case.
Any pointers?
