[R] Hotelling T2 test extension for multigroup data

[Vickie S]

Hi all,
I've got the following matrix :
 
mat <- matrix(rnorm(700), ncol=5, dimnames=list( paste("f", c(1:140), sep="_"), c("A", "B", "C", "D", "E")))

I can see that currently most of the multivariate Hotelling T2 tests are limited for application on two groups/samples. 

I wud appreciate if someone can provide me a suggestion how to implement the same for multiple groups.


Thx,
- Vickie
