The Davidson-Harel layout algorithm

Source: R/layout.R
layout.davidson.harel.Rd

[Deprecated]

layout.davidson.harel() was renamed to layout_with_dh() to create a more consistent API.

Usage

layout.davidson.harel(
  graph,
  coords = NULL,
  maxiter = 10,
  fineiter = max(10, log2(vcount(graph))),
  cool.fact = 0.75,
  weight.node.dist = 1,
  weight.border = 0,
  weight.edge.lengths = edge_density(graph)/10,
  weight.edge.crossings = 1 - sqrt(edge_density(graph)),
  weight.node.edge.dist = 0.2 * (1 - edge_density(graph))
)

Arguments

graph

The graph to lay out. Edge directions are ignored.

coords

Optional starting positions for the vertices. If this argument is not NULL then it should be an appropriate matrix of starting coordinates.

maxiter

Number of iterations to perform in the first phase.

fineiter

Number of iterations in the fine tuning phase.

cool.fact

Cooling factor.

weight.node.dist

Weight for the node-node distances component of the energy function.

weight.border

Weight for the distance from the border component of the energy function. It can be set to zero, if vertices are allowed to sit on the border.

weight.edge.lengths

Weight for the edge length component of the energy function.

weight.edge.crossings

Weight for the edge crossing component of the energy function.

weight.node.edge.dist

Weight for the node-edge distance component of the energy function.
