[R] Save Cluster results to data frame

[Christian Hennig]

Hi Chris,

this isn't particularly a clustering question, is it?

Why don't you just take your clustering vector 
(pam.output.object$clustering) and assign it to 
a$clustering (given that a is the name of your data frame)?

And why don't you just define a new character/string vector and assign
the cluster names that you want to it using if or case?

Regards,
Christian
