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")

Subject: [BioC] hierarchical clustering - spearman correlation
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?
