Draw dendrogram plots in a track

Object ccCellGeom will call the function circlize::circos.dendrogram while drawing.

Usage

ccDendrogram(...)

Arguments

...

Arguments passed on to circlize::circos.dendrogram

dend

A dendrogram object.

facing

Is the dendromgrams facing inside to the circle or outside?

max_height

Maximum height of the dendrogram. This is important if more than one dendrograms are drawn in one track and making them comparable. The height of a dendrogram can be obtained by attr(dend, "height").

use_x_attr

Whether use the x attribute to determine node positions in the dendrogram, used internally.

sector.index

Index of sector.

track.index

Index of track.

Value

Object ccCellGeom
