Hello, I was wondering if there is any package with several metrics for cluster estimation (estimating the k=2...10) (or evaluation..). Also if instead of euclidean distance in k-means I use some other kind of distance.. then for those evaluation metrics which takes into consideration the distance (n^2) matrix, i should also use that same distance metric i used for clustering? Or should i always use the euclidean? Thanks [[alternative HTML version deleted]]
