[R] Are any values in one list contained within a second list

Silly question, but, can I test to see if any value of list a is contained in
list b without doing a loop? A loop is easy enough, but wanted to see if
there was a cleaner way. By way of example:

List 1: a, b, c, d, e, f, g

List 2: z, y, x, w, v, u, b

Return true, since both lists contain b

List 1: a, b, c, d, e, f, g

List 2: z, y, x, w, v, u, t

Return false, since the lists have no mutual values
