xnet: Network embedding

In amen: Additive and Multiplicative Effects Models for Networks and Relational Data

Network embedding

Description

Compute an embedding of a sociomatrix into a two-dimensional space.

Usage

xnet(
  Y,
  fm = try(requireNamespace("network", quietly = TRUE), silent = TRUE),
  seed = 1
)

Arguments

Y	(square matrix) The sociomatrix.
fm	(logical scalar) If TRUE, the Fruchterman-Reingold layout will be used (requires the network package).
seed	(integer) The random seed (the FR layout is random).

Details

Coordinates are obtained using the Fruchterman-Reingold layout if the package network is installed, and otherwise uses the first two eigenvectors the sociomatrix.

Value

(matrix) A matrix of two-dimensional coordinates.
