Compute an embedding of a sociomatrix into a two-dimensional space.
Usage
xnet(
Y,
fm = try(requireNamespace("network", quietly = TRUE), silent = TRUE),
seed = 1
)
Value
(matrix) A matrix of two-dimensional coordinates.
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).
Author
Peter Hoff
Details
Coordinates are obtained using the Fruchterman-Reingold layout if the
package network is installed, and otherwise uses the first two
eigenvectors the sociomatrix.
