hang.dendrogram: Hang dendrogram leaves

Description

Adjust the height attr in all of the dendrogram leaves so that the tree will hang. This is similar to as.dendrogram(hclust, hang=0.1) Only that it now works on other object than hclust turned into a dendrogram. For example, this allows us to hang non-binary trees.

Usage

hang.dendrogram(dend, hang = 0.1, hang_height, ...)

Arguments

dend

a dendrogram object

hang

The fraction of the plot height by which labels should hang below the rest of the plot. A negative value will cause the labels to hang down from 0.

hang_height

is missing, then using "hang". If a number is given, it overrides "hang" (except if "hang" is negative)

...

not used

Value

A dendrogram, after adjusting the height attr in all of its leaves, so that the tree will hang.

Examples

# NOT RUN {
# define dendrogram object to play with:
hc <- hclust(dist(USArrests[1:5,]), "ave")
dend <- as.dendrogram(hc)

par(mfrow = c(1,2))
plot(hang.dendrogram(dend))
plot(hc)
# identical(as.dendrogram(hc, hang = 0.1), hang.dendrogram(dend, hang = 0.1))
# TRUE!!


par(mfrow = c(1,4))

plot(dend)
plot(hang.dendrogram(dend, hang = 0.1))
plot(hang.dendrogram(dend, hang = 0))
plot(hang.dendrogram(dend, hang = -0.1))

par(mfrow = c(1,1))
plot(hang.dendrogram(dend), horiz = TRUE)
 
 
# }
