Subject: Help understanding cutree used for Dunn Index
In-Reply-To: <650af817-4436-4371-b765-c067ac3c574c@n10g2000vbg.googlegroups.com>

I found a way to draw rectangles around whatever cutree cuts, so I think I 
now have a better idea, which is that it looks for the largest k distances 
and cuts there, where k is the # clusters you want defined. Then, I assume 
Dunn index uses the same defined #clusters to determine within vs. across 
cluster similarities (i.e. distances).

If I'm way off please let me know, otherwise thanks for taking the time to 
read my question.
