Hi all,
Well, I just sent a help msg to the list with this subject,
but I think I figured out a way to solve my problem
(although I still have no clue if the behavior I described
is correct).
What I did was to replace occurrences of (for example)
cov(x[sub, ])
with
cov(matrix(x[sub, ], ncol=ncol(x))
It works.
I updated my source version of the cclust package. It
may be of interest to somebody else, but I don't know
how to submit to the package mantainer.
Thank you.
