you need to keep in mind that these are two separate things: calculation
of the distance matrix (i.e. distance between each gene to every other
gene), and the actual clustering algorithm to make this matrix into a
You can use for example "cor" to calculate correlations including
"pearson", "kendall", "spearman", and "hclust" to do the clustering.
