Hi R helpers... I am having troubles because of the discrepancy  
between the dendrogram plotted from hclust and what is wrote in the  
hc2Newick file. I've got a matrix C:

> hc <- hclust(dist(C))
> plot(hc)

with the:

> write(hc2Newick(hc),file='test.newick')

both things draw completely different "trees"...

I have also tried with the raw distance matrix D and also the agnes  
function, but the same happens. The hclus and agnes dendrogram is  
logical, whereas the newick tree is not.

Thanks for any help!
