Power analysis for MANOVA?
http://www.amazon.com/Statistical-Power-Analysis-Behavioral-Sciences/dp/0805802835 Cohen's book was in fact the basis for the "pwr" package at CRAN. And it does have a MANOVA power analysis, which was left out of the "pwr" package.

Hello,
I have searched and failed for a program or script or method to
conduct a power analysis for a MANOVA. My interest is a fairly simple case
of 5 dependent variables and a single two-level categorical predictor
(though the categories aren't balanced).
If anybody happens to know of a script that will do this in R, I'd
love to know of it! Otherwise, I'll see about writing one myself.
What I currently see is this, from help.search("power"):
stats::power.anova.test
Power calculations for balanced one-way
analysis of variance tests
stats::power.prop.test
Power calculations two sample test for
proportions
stats::power.t.test Power calculations for one and two sample t
tests
Any references on power in MANOVA would also be helpful, though of
course I will do my own lit search for them myself.
Cordially,
Adam D. I. Kramer
