layout_igraph_dendrogram: Apply a dendrogram layout to layout_igraph

In YTLogos/ggraph: An Implementation of Grammar of Graphics for Graphs and Networks

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.

Note

This function is not intended to be used directly but by setting layout = 'dendrogram' in create_layout
