Ideally you'd upgrade your version of R (to 2.9.0) as well,

aaah.. now we are getting somewhere:
It looks you have alway

distance between your observational units,
After that you can use the computed distance / dissimilarity matrix
(the `dx`) in you call to pam():
px <- pam(dx, k=., )
I hope this helps you.

ifelse() is very much over-used!

In R, these both are function calls:
