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 =
> dCol <- dist(t((1- cor(esetSub2X))),method =

> 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,
