Hello, I am looking for documentation (PDF ?) about doing clustering with the EM Algorithm on R... I'm sorry for this question which may be trivial... Thanks... Dominique

From ?Mclust: Clustering via EM initialized by hierarchical clustering for parameterized Gaussian mixture models. The number of clusters and the clustering model is chosen to maximize the BIC.

Hi, Check out the docs of the mclust and FlexMix packages: http://www.stat.washington.edu/mclust/ http://www.ci.tuwien.ac.at/~leisch/FlexMix/ Xtof.
