extracting groups from hclust() for a very large matrix
...t;- vegdist(VTM.Matrix)
> VTM.HClust<- hclust(VTM.Dist, method="ward")
> plot(VTM.HClust, hang=-1)
It takes a while, but it does run. Then, I can extract 8 groups, which
I'd like to experiment with, but is about how many I'd like:
rect.hclust(VTM.HClust, 8)
> VTM.8groups<- cutree(VTM.HClust, 8)

137 173 239 356 709 585 908 1264
The vegemite() function also doesn't work f...
