I have the code below but the p-values are not what I am expecting. I want
to use the Cochran Armitage trend test to get the p-values.

What do you expect? Depending on the genetic model, you may not see HWE in the
"cases".

datamat[h,] <- t(rmultinom(1, size=c(10, 40, 50), prob=c(0.33, 0.33, 0.34)))

"size" should be the total size ie 100.
