Dear R-help..

I am rather new in R so i would appreciate your help in my problem..

I have 3 types of vegetation (A,B,C),50 measurements per class and 100 variables
per measurement.
I would like to perform seperability analysis between these classes meaning...

a.)create the hypercube from these 100 variables
b.)"plot" the 50 measurements for each class and identify the position of the
center of each class..
c.)calculate the distances between each class center using Euclidean,
Jeffries-Matusita or other measures.

I have tried searching all keywords at CRAN but i was not able to find a post or
a package that could be used for an analysis like that..

I would appreciate your help...

Kind regards to all R-helpers..

Achilleas.
