centroids

It evaluates the centroids of a partition with the weights in <code>rw</code>

multivariate

Some functions of 'ade4' and 'stats' are combined in order to obtain
a partition of the rows of a data table, with columns representing
variables of scales: quantitative, qualitative or frequency.
First, a principal axes method is performed and then, a combination
of Ward agglomerative hierarchical classification and K-means is
performed, using some of the first coordinates obtained from the
previous principal axes method.
In order to permit different weights of the elements to be clustered,
the function 'kmeansW', programmed in C++, is included.
It is a modification of 'kmeans'. Some graphical functions include
the option: 'gg=FALSE'.  When 'gg=TRUE', they  use the 'ggplot2'
and 'ggrepel' packages to avoid  the super-position of the labels.
