permute_graph: Permute the values of a matrix

Description

permute_graph Shuffles the values of a matrix either considering loops and multiple links (which are processed as cell values different than 1/0). rewire_qap generates a new graph graph\('\) that is isomorphic to graph.

Usage

permute_graph(graph, self = FALSE, multiple = FALSE)
rewire_permute(graph, self = FALSE, multiple = FALSE)
rewire_qap(graph)

Value

A permuted version of graph.

Arguments

graph

Any class of accepted graph format (see netdiffuseR-graphs).

self

Logical scalar. When TRUE autolinks (loops, self edges) are allowed (see details).

multiple

Logical scalar. When TRUE allows multiple edges.

Examples

# Simple example ------------------------------------------------------------
set.seed(1231)
g <- rgraph_ba(t=9)
g

# These preserve the density
permute_graph(g)
permute_graph(g)

# These are isomorphic to g
