[R] Cluster Analysis: Density-Based Method

[Fernando Prass]

Andy,

I can be wrong, I'm no expert too, but density estimation is different of
density-model. MClust is a model-basead method because use model statistics
from clustering data (more information in
ftp://ftp.u.washington.edu/public/mclust/tr415R.pdf).

I need some package that implement algorithms like OPTICIS, DBSCAN or
DENCLUE...
