Dear list, is there a way how to add information to internal nodes (branching points) in dendrogram created via plot.agnes function (package cluster)? I wish to place colored circles on the nodes, but I don't know how to proceed... I'll be grateful for any suggestion Ondřej
Example: data(votes.repub) agn1 <- agnes(votes.repub, metric = "manhattan", stand = TRUE) plot(agn1, which=2) Now take a look, all information is available from the agnes object: str(agn1) and you can, for example, mark the most left branch point with: points(1.5, agn1$height[1], col="red") Best, Uwe Ligges ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
