I believe that this method also requires that foo2 be a one-to-one mapping of the elements in foo1, and fails for example, to find the matching 'e' values in the two vectors:

foo1 = ['b','c','d','e']
foo2 = ['a','e','f','g']

And even some of us who use it often, forget that it can be used with strings. --Wayne
