How about a trick?

A quick question for the gurus...
Given:
a=c(58,73,100,40,70)
b=c(40,70,73,100,58,70,70,58)
How can I replace the elements of "b" with the corresponding index
numbers from "a" that start at 1? All values in "a" are unique. So, I
end up with:
b=c(4,5,2,3,1,5,5,1)
I believe I need to use one of
4 matches
