[R] Document clustering for R

[Raymond K Pon]

I'm working on a project related to document clustering. I know that R 
has clustering algorithms such as clara, but only supports two distance 
metrics: euclidian and manhattan, which are not very useful for 
clustering documents. I was wondering how easy it would be to extend the 
clustering package in R to support other distance metrics, such as 
cosine distance, or if there was an API for custom distance metrics.

Best regards,
