test for equality of two data sets with multidimensional variables
Hello there,
I have two data sets with 14 variables each, and wish to do the test
for equality of their covariance matrices and mean vectors. Normally
these tests should be done by chi square test (box provided) and
Hotelling's T square test respectively. Which R functions could do
this kind of test? I just find some functions could do for one
dimension, but no for multidimension. Some one

MANOVA extension of paired t-test?
I would like to test the hypothesis that the difference between pairs, for
several variables, is zero. This is easily done separately for each
variable with:
lm(Y ~ rep(0, nrow(Y)))
where Y is a matrix whose columns are the differences for each variable
between pair members.
However, I would like to get an overall probability across all variables
from a Wilks or Pillai-Bartlett statistic as in
