Help: Mahalanobis distances between 'Species' from iris
...1
Versicolor 89.86419 0 17.20107
Virginica 179.38471 17.20107 0
This distances above were obtained with proc 'CANDISC' of SAS, please,
see Output 21.1.2: Iris Data: Squared Mahalanobis Distances from
http://www.id.unizh.ch/software/unix/statmath/sas/sasdoc/stat/chap21/sect19.htm
From this distance my intention is to make a cluster analysis as below, using
the package 'mclust':
#
# --- Begin R script ---
#
# For units compatibility of 'iris' from R dataset and 'iris' data used in
# the SAS example:
Measures = iris[,1:4]*10
Species = iris[,5]...

In prior mail, my basic question was: how to obtain this matrix with R
from 'iris' data?
Well, I think that the basic soluction to calculate this distances is:
