[R] Mann-Whitney U Table

Does anyone have a piece of code or know how I can use R to generate a table
critical values for the Mann-Whitney (aka Wilcoxon Rank Sum) test.

Ideally, I'd like a table that contains the critical values for any two
samples of size 3 through 30.  I could use Monte Carlo simulation or the
normal approximation when n1 and n2 are greater than, 10, but I figured
someone may know how to calculate these exactly.
