[R] dendrogram branches with different lty

[Patrick Kuss]

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))
plot(dend1)
plot(dend1[[1]],edgePar=list(lty=3))
plot(dend1[[2]],edgePar=list(lty=1))
