Dear R-helpers, I am writing to the list in order to inquire whether there exists any R package or program that will help me "describe" clusters. The situation is as follows: 1) I create some clusters (say, with any clustering method in R). 2) I want to "describe" and assign some kind of "label" to each of them. In order to "label" each cluster, I want to compare the distribution of the variables in each cluster with respect to the distribution of the variables in the original dataset. I would like to do it graphically, if possible. In this way I could review this output and say: this cluster corresponds to, say, "older patients who were not treated before", etc. I am aware this is not sound scientific practice, but I am asked to do something like that. I have some ideas about how to do it, but I would like to know if I am walking on a well trodden path. Best regards, Carlos J. Gil Bellosta http://www.datanalytics.com
