Hi!
In the example:
hc <- hclust(dist(USArrests), "ave")
dend1 <- as.dendrogram(hc)
dend2 <- cut(dend1, h=70)
Do the branches "Branch 1", "Branch 2", "Branch 2"...in dend2$upper
str(dend2$upper)
--[dendrogram w/ 2 branches and 4 members at h = 152]
|--[dendrogram w/ 2 branches and 2 members at h = 77.6]
| |--leaf "Branch 1" (h= 38.5 midpoint = 0.5, x.member = 2 )
| `--leaf "Branch 2" (h= 44.3 midpoint = 5.03, x.member = 14 )
`--[dendrogram w/ 2 branches and 2 members at h = 89.2]
|--leaf "Branch 3" (h= 44.8 midpoint = 6.8, x.member = 14 )
`--leaf "Branch 4" (h= 54.7 midpoint = 7.65, x.member = 20 )
correspond to the classes 1, 2, 3... in dendclass, where
dendclas <- cutree(hc,h=70)
?
If they do not, how can I get a vector with the original individuals
for each branch?
Thanks
Agus
