layout_igraph_centrality: Centrality layout

Description

arranges nodes in concentric circles according to a centrality index

Usage

layout_igraph_centrality(g, cent, scale = T, iter = 500, tol = 1e-04,
  tseq = seq(0, 1, 0.2), circular)
layout_with_centrality(g, cent, scale = T, iter = 500, tol = 1e-04,
  tseq = seq(0, 1, 0.2))

Arguments

g

igraph object

cent

centrality scores

scale

scale centrality between 0 and 100?

iter

number of iterations

tol

stopping criterion

tseq

transition steps

circular

not used

Value

coordinates to be used layouting a graph

Details

the layout_igraph_* function should not be used directly. It is only used as an argument for 'ggraph'.
