Draw dendrogram plots in a track

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

Usage

ccDendrogram(
  dend,
  facing = c("outside", "inside"),
  max_height = NULL,
  use_x_attr = FALSE
)

Arguments

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.

Value

Object ccCellGeom
