spiral_dendrogram {spiralize}

Draw dendrogram

Description

Draw dendrogram

Usage

spiral_dendrogram(dend, gp = gpar(), track_index = current_track_index())

Arguments

dend

A stats::dendrogram object.

gp

Graphical parameters of the dendrogram edges, mainly as a global setting.

track_index

Index of the track.

Details

Graphical parameters for individual edges can be set via the edgePar attribute on each node in the dendrogram, see stats::dendrogram for how to set edgePar.

The dendrogram edges can also be rendered by dendextend::color_branches().

Value

Height of the dendrogram.

Examples

k = 500
dend = as.dendrogram(hclust(dist(runif(k))))
spiral_initialize(xlim = c(0, k), start = 360, end = 360*3)
spiral_track(height = 0.8, background_gp = gpar(fill = "#EEEEEE", col = NA))
spiral_dendrogram(dend)


require(dendextend)
dend = color_branches(dend, k = 4)
spiral_initialize(xlim = c(0, k), start = 360, end = 360*3)
spiral_track(height = 0.8, background_gp = gpar(fill = "#EEEEEE", col = NA))
spiral_dendrogram(dend)
