Hi , How can I get dChip clustering on heatmap?..which is nice & easy to see patterns. I am using 1- cor(eset) but somehow its not working I am still getting diff. kind of clustering dendrogram. > d <- dist((1 - cor(esetSub2X)),method = "euclidean"); > dCol <- dist(t((1- cor(esetSub2X))),method = "euclidean"); > heatmap(esetSub2X,Colv= as.dendrogram(hclust(d,method = "complete")),Rowv = NA,col = rbg,cexRow = 1,cexCol = 1); Am I missing something? Any heatmap clustering is helpful. Thank you, Saurin __________________________________ The all-new My Yahoo! - Get yours free!
