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? David Scott --
