flatten.dendrogram

Flatten the branches of a dendrogram's root

Description

The function makes sure the two branches of the root of a dendrogram will have the same height. The user can choose how to decide which height to use.

Usage

flatten.dendrogram(dend, FUN = max, new_height, ...)

Arguments

`dend`	dendrogram object
`FUN`	how to choose the new height of both branches (defaults to taking the max between the two)
`new_height`	overrides FUN, and sets the new height of the two branches manually
`...`	passed on (not used)

Value

A dendrogram with both of the root's branches of the same height

Examples

hc <- hclust(dist(USArrests[2:9, ]), "com")
dend <- as.dendrogram(hc)
attr(dend[[1]], "height") <- 150 # make the height un-equal

par(mfrow = c(1, 2))
plot(dend, main = "original tree")
plot(flatten.dendrogram(dend), main = "Raised tree")
