Please to both of you: check the advice in the R 2.5.0 alpha version of
the rw-FAQ. That has worked for everyone else who has reported a problem
with installing packages on Vista.
I've placed a copy online at

My simple problem is that when i run kmeans this give me different results
because if centers is a number, a random set of (distinct) rows in x is
chosen as the initial centres.
About me the problem is simple.
The question i ask you is if it possible that centers could be different
from number.
