Hello Martin Maechler and All,

A simple question (I hope):
How can I compute the "sum of the dissimilarities" that appears in the pam
command (from the cluster package) ?

Is it the "manhattan" distance (such as the one implemented by "dist") ?


I am asking since I am running clustering on a dataset. I found 7 medoids
with the pam command, and from it I have the medoid to which each
observation belongs to. But when I check it, I find only (about) 90% of
observations has the minimum manhattan distance to the medoids that pam
predicted.

If this is the manhattan distance that is used, I will create some toy data
to see if I can reproduce this.

Thanks,
Tal
