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)) plot(dend1) plot(dend1[[1]],edgePar=list(lty=3)) plot(dend1[[2]],edgePar=list(lty=1))
try
dend1[[1]] <- dendrapply(dend1[[1]], function(e) { attr(e, "edgePar") <- list(lty=3); e })
plot(dend1)
