[BioC] som - can it divide the samples into clusters

Hi,

Such as in Golub data, he divide the data into four groups by setting the group number as 4 in SOM. IF I use condition tree or principal component analysis, I can not set the group number by myself.

Hi,

You can cluster the samples in GS by using the condition tree and find
out the relations from the branch length or use principal component
analysis.

Dear all,

Somebody used a SOM to divide the samples into clusters. However the
SOM in GeneSpring only divides the genes into clusters, not samples. I
wonder the SOM in R can divide the samples? Or anybody knows a SOM can
do this work? Thanks a lot!
