ggraph (version 1.0.2)

layout_igraph_dendrogram: Apply a dendrogram layout to layout_igraph

Description

This layout mimicks the layout_as_tree algorithm supplied by igraph, but puts all leaves at 0 and builds it up from there, instead of starting from the root and building it from there. The height of branch points are related to the maximum distance to an edge from the branch node.

Usage

layout_igraph_dendrogram(graph, circular = FALSE, offset = pi/2,
  direction = "out")

Arguments

graph

An igraph object

circular

Logical. Should the layout be transformed to a circular representation. Defaults to FALSE.

offset

If circular = TRUE, where should it begin. Defaults to pi/2 which is equivalent to 12 o'clock.

direction

The direction to the leaves. Defaults to 'out'

Value

A data.frame with the columns x, y, circular and leaf as well as any information stored as vertex attributes on the igraph object.
