[R] heatmap scale parameter

[Witold E Wolski]

does change only the colors but dendrograms are unaffected.

d <- matrix(rnorm(100),nrow=20)
heatmap(d)
heatmap(d,scale="column")
heatmap(d,scale="row")
heatmap(d,scale="none")


However scaling clearly affects clustering. see:

d <- scale(d)
heatmap(d,scale="none")
