Hi
When I use plot(hclust(dist..)...)...) etc to create a dendrogram of a hierarchial cluster analysis, I end up with a vertical tree. What do I need to do to get a horizontal tree?
Also, my users are used to seeing trees who's leaves all "end" at the same place (eg. Like in minitab). Is this possible in R?
Thanks
Mick
Mick,
If you use as.dendrogram first then the plot method for dendrograms has a horizontal option:
data(USArrests) hc <- hclust(dist(USArrests), "ave") dend1 <- as.dendrogram(hc) plot(dend1, horiz = TRUE)
This also puts the leave at the end.
