[BioC] hierarchical clustering - spearman correlation

[michael watson (IAH-C)]

Hi

If x is my data matrix:

c <- cor(x, method="spearman")
d <- as.dist(1-c)  # because correlation is a similarity measure and you
want a distance
hc <- hclust(d, method="complete")

Dear all,

There are many libraries for the hierarchical clustering in R. However,
I can not find one hierarchical clustering by specifically using
spearman correlation. Does any experienced guy provide some information?

Thank you!
