how to colour labels (each label with a colour) in a dendrogram?
Hello to all,
I still have this doubt.
I'd like to colour the different labels of my dendrogram each one with a
different colour. How can I do? I guess I could do using *edgetext* and
then *t.col* or* lab.col* but I don't know how to add edgetext to my
dendrogram. Can you help me please?
Example:
require(graphics); require(utils)
hc <- hclust(dist(USArrests), "ave")

plot.dendrogram
Dear R-users,
I would like to change the labels size and format in the node ends of a dendrogram, how can I do it?
How can I use different symbols/colors in each node ends ?
I manage to do it with plot.cluster, but heat map uses plot.dendrogram.
Can anyone help me please?
thank you

dendrogram branches with different lty
Dear r-list,
I am trying to visually seperate the two main clusters of a dendrogram.
The idea is to use:
'edgePar=list(lty=3)' for 'dend1[[1]]' and
'edgePar=list(lty=1)' for 'dend1[[2]]'
I have not found a way to solve this. Any suggestions?
Patrick
hc <- hclust(dist(USArrests), "ave")
(dend1 <- as.dendrogram(hc))
par(mfrow=c(2,2))

dendrogram plot does not draw long labels ?
Hello,
It seems that the plot function for dendrograms does not draw labels when
they are too long.
> hc <- hclust(dist(USArrests), "ave")
> dend1 <- as.dendrogram(hc)
> dend2 <- cut(dend1, h=70)
> dd <- dend2$lower[[1]]
> plot(dd) # first label is drawn
> attr(dd[[1]], "label") <- "aaaaaaaaaaaaaaaaaa"
> plot(dd) # first label is
