edge_bundle_path: Edge-Path Bundling

In schochastics/edgebundle: Algorithms for Bundling Edges in Networks and Visualizing Flow and Metro Maps

Edge-Path Bundling

Description

Implements edge-path bundling.

Usage

edge_bundle_path(
  g,
  xy,
  max_distortion = 2,
  weight_fac = 2,
  segments = 20,
  bundle_strength = 1,
  mode = "out"
)

Arguments

g	an igraph object
xy	coordinates of vertices
max_distortion	maximum distortion
weight_fac	edge weight factor
segments	number of subdivisions of edges
bundle_strength	bundle strength factor
mode	the parameter fo shortest_paths
