get_branches_heights(dend, sort = TRUE, decreasing = FALSE,
  include_leaves = FALSE, ...)

Arguments

dend

a dendrogram.

sort

logical. Should the heights be sorted?

decreasing

Examples

# NOT RUN {
hc <- hclust(dist(USArrests[1:4,]), "ave")
dend <- as.dendrogram(hc)
get_branches_heights(dend)

# }
# NOT RUN {
dat1 <- iris[1:150,-5]
dat1 <- rbind(dat1,dat1,dat1,dat1,dat1,dat1,dat1)
dend = as.dendrogram(hclust(dist(dat1)))
