Hello everybody
I'have a general question about the heatmap function. I'm clustering
an
expression matrix with different dissimilarity measures. Correct if
I'm
wrong but if I want to cluster the columns I have to scale the rows to
bring the genes to a common range, and this is apparently the default
behavior of heatmap (according to the option scale="row"). So I
expected
to see different dendrograms, setting scale="none", but there's no
change. It seems that the scaling only affects the plotting but not
the
generation of dendrograms. Where's the mistake?
Thank you in advance
Best regards
