[BioC] Fwd: heatmap.2 question

[Wang, Li]

Hi, Alyaa

Assuming that you have an object "hr" which clusters rows by spearman correlation as distance method, 
hr <- hclust(as.dist(1-cor(t(y), method="spearman")), method="complete"), y is your matrix here.

hr$labels[hr$order] 
it will print the row labels in the order they appear in the tree. 

I donot know if this is what you want. 

Best
Li

Subject: [BioC] Fwd: heatmap.2 question

Hi All

How can I possibly extract the clusters by rows from a heatmap generated by
heatmap.2 function. i.e. the heatmap is generated with colouring for every
cluster of rows and I want to retrieve the members of each cluster.


Any clue would be much appreciated

Thank you very much
