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")
(dend1 <- as.dendrogram(hc))
plot(dend1)
labels (USArrests) [[1]] # to know how many cities (labels) = 50
nP <- list(col=3:2, cex=c(2.0, 0.75), pch= 21:22,
bg= c("light blue", "pink"),
lab.cex = 0.75, lab.col = 1:50) # or use a palette:
palette(rainbow(50))
plot(dend1, edgePar=nP, dLeaf=1, edge.root = TRUE)
# this option is not correct. I want each of my labels (text) have a
different colour but that is not what is happening. How can I do that?
I'd appreciate your help.
thanks a lot again.
Barbara
