[R] Persp Plot
I am trying to graph two planes on the same graph using persp(). I can only get one plane to plot at a time. Can someone explain how I can graph two planes on the same graph using persp? I've looked throught the documentation, but cannot find any references to appending a persp plot. Thanks. Sincerely yours, Mark J.

Any suggestions if they are intersecting? Thanks. Sincerely yours, Mark J.

See example(wireframe).

[R] Mann-Whitney U Table
Does anyone have a piece of code or know how I can use R to generate a table of 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. Thanks. Sincerely yours, Mark J.
