[R] cluster in R

[Weiwei Shi]

hi,

is there some good summary on clustering methods in R? It seems there
are many packages involving it.

And I have two questions on clustering here:

1. Is there a way of evaluate the effecitives (or seperation) of
clustering (rather than by visualization)?

2. Is there a search method (like genetic search) which can help find
the best subset of attributes which gives best seperation?

Thanks,
