It might be interesting to look at this from the pam()
perspective:
What exactly is pam() lacking that kmeans() does for you?
Christian, are you suggesting that pam() could do the job if
1) there was a dist(., method="a la kmeans")
2) pam() allowed to be started by a user-specified set of
medoids instead of the "Kaufman-Rousseeuw-optimal" ones
?
