R help - Aug 2004 - distance to cluster center

Is there a way to get the distance between each point and the center of
the cluster it was assigned to in cluster methods such as agnes, pam,
and clara.

 

Thanks!

I don't think that it's directly available, but for pam and clara you
can
easily get it from your dissimilarity matrix using the information
given in the components clustering and
medoids of the output object (see ?pam.object, ?clara.object).

For hierarchical clustering methods as implemented in agnes, there is no
such thing as a well defined cluster center.
