[R] Paper on PAM and Clara

[Fucang Jia]

Hi, everyone,

I found that Clara and Pam is very useful in large data clustering. So I 
want to learn more about it. But as far as I know, the idea is comes the 
authors' book "Finding groups in data: an introduction to cluster analysis". 
Unfortunately, I have no access to this book. Could anyone tell me that if 
there are other papers which descirbes these methods?

Thank you very much!

Best,

Fucang
