[R] Matching pairs of values

[David Scott]

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?
