layout_tbl_graph_eigen: Place nodes according to their eigenvalues

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

Place nodes according to their eigenvalues

Description

This layout is based on the idea of spectral layouts where node coordinates are calculated directly by decomposing a matrix representation of the graph and extracting the eigenvectors.

Usage

layout_tbl_graph_eigen(
  graph,
  type = "laplacian",
  eigenvector = "smallest",
  circular = FALSE
)

Arguments

graph	A tbl_graph object
type	The type of matrix to extract the eigenvectors from. Either 'laplacian' or 'adjacency'
eigenvector	The eigenvector to use for coordinates. Either 'smallest' or 'largest'
circular	ignored

Value

A data.frame with the columns x, y, circular 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
