clustering with hclust
...the squared euclidean distances from cosines
(d=2(1-cos)) produces a different outcome.
As a consequence, using hclust with ward method on a table of cosines
tranformed into distances with dist, produces a different dendrogram than
other programs for hierarchical clustering with ward method (i.e.
multidendrograms). Weird right??
Computing manually the distances and then feeding them to hclust produces
an error message. So, I am wondering, what the hell is this dist function
doing?!
thanks!
