Hi!
I am newbee to R and I am facing the problem in plotting
the dedrogram with lot of objects. The lines and labels are overlapped very
badly, and writing the graphic to postscript and zooming there is not helping
either. I tried cut.dendrogram method, but getting the error that it doesn't
exist even though I get the man pages for it.
I would not find any solution in web as well, and I would be grateful to you
if you would share your thoughts or solutions with me.
Here is my code:
A <- read.table("temp.csv", sep =",", header =TRUE,
row.names = 1)
hc <- hclust(dist(A),method='single')
plot(as.dendrogram(hc), horiz=TRUE, cex=0.2)
memb <- cut.dendrogram(as.dendrogram(hc), 4)
Error: couldn't find function "cut.dendrogram"
Thanks allot,
Samatha

I think you need to use just:
cut
You may also want to look at:
cutree
