[BioC] heatmap genenames

Hi everyone,

we've been looking at something similar to try to pick single a series
of genes from the heatmap.

Based on Michael's suggestion:

d <- dist(mydata)
hc <- hclust(d)
heatmap(mydata, RowV=as.dendrogram(hc))


So you can select the branch(es) of interest on the dendogram and get
back the list of genes selected.
