R Documentation

Place nodes in circles according to centrality measure

Description

This layout places nodes in circles with the radii relative to a given centrality measure. Under the hood it use stress majorisation to place nodes optimally given the radius constraint.

Usage

layout_tbl_graph_centrality(graph, centrality, scale = TRUE,
  niter = 500, tolerance = 1e-04, tseq = seq(0, 1, 0.2),
  circular = FALSE)

Arguments

`graph`	A tbl_graph object
`centrality`	An expression evaluating to a centrality measure for the nodes. See the different `centrality_*()` algorithms in tidygraph for a selection.
`scale`	Should the centrality measure be scaled between 0 and 100
`niter`	number of iterations during stress optimization
`tolerance`	stopping criterion for stress optimization
`tseq`	Transitioning steps
`circular`	ignored

Value

A data.frame with the columns x, y, circular, centrality as well as any information stored as node variables in the tbl_graph object.

Author(s)

The underlying algorithm is implemented in the graphlayouts package by David Schoch
