Dear List, I have another question to bother you about how to do clustering. My data consists of 49 columns (49 variables) and 238804 rows. I would like to do hierarchical clustering (unsupervised clustering and PCA). So far I tried pvclust (www.is.titech.ac.jp/~shimo/prog/ *pvclust* /) but I always had the problem like for R like "cannot allocate the memory". I am curious about what else packages can perform the clustering analysis while memory efficient. Meanwhile, is there any way that I can extract the features of each cluster. In other words, I would like to identify which are responsible for classifying these variables (samples). Thanks a lot! Sincerely, Alex [[alternative HTML version deleted]]
