xnet: Network embedding

Description

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

Usage

xnet(Y, fm = suppressWarnings(require("network")), 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).

Value

(matrix) A matrix of two-dimensional coordinates.

Details

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

Examples

data(addhealthc3)
Y<-addhealthc3$Y
X<-xnet(Y)
netplot(Y,X)
