R: Flatten the branches of a dendrogram's root

flatten.dendrogram {dendextend} | R Documentation

## 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")
