[R] Validation of clustering

[Christian Hennig]

Hi,

I am not really sure what you want to know. 
If you simply want to know how to find the resulting clustering, consider
help(clara.object). For validation and assessment of the clustering, you
might use a silhouette plot, see help(plot.partition),
help(partition.object). 

For more descriptions consider the book of Kaufman and Rousseeuw; some free
material is on
http://win-www.uia.ac.be/u/statis/index.html
(Programs->Clustering)

Best,
Christian
