network.update: Replaces the sociomatrix in a network object

Description

Replaces the sociomatrix in a network object with the sociomatrix specified by newmatrix. See ergm for more information.

Usage

network.update(nw, newmatrix, matrix.type=NULL, output="network")

Arguments

nw

a network object. See documentation for the network package.

newmatrix

Either an adjacency matrix (a matrix of zeros and ones indicating the presence of a tie from i to j) or an edgelist (a two-column matrix listing origin and destination node numbers for each edge; note that in an undirected matrix, the first column sh

matrix.type

One of "adjacency" or "edgelist" telling which type of matrix newmatrix is. Default is to use the which.matrix.type function.

output

Currently unused.

Value

• network.update returns a network object.
