Hi,

I'm new to R; this is my second email to this forum. I have a dataset that looks like this:

Gene                            A                     B
C                     D



A                                 511                  6116
1515                1515

B                                  164                  115
1515                494

C                                 21646

D                                 1616

E                                  1461

F

G

H

There are about 40000 genes with 3-10 patients per dataset. Gene expression values fill the matrix.

I want to do a simple hierarchical clustering along BOTH rows and columns and get a tree dendrogram output for both in one panel.

Is there a simple code for this, leaving out fancy options?

Thank you very much.

-DS.
