Hi ! I have two different questions: 1) is it possible to obtain automatically the whithin cluster sum of squares with PAM procedure ? In kmeans this was easy: kmeans_object$withinss. 2) are there in R procedure of density based clustering like DBSCAN, OPTICS, and DENCLUE ? Thanks in advance, Paola. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
