choose.edges selects edges to be re-wired when simulating random
graphs while controlling for clustering. It is based on the algorithm
by Bansal et al. (2009), BMC Bioinformatics.
choose.edges(A, degs.large)Numeric (adjacency) matrix
Integer vector of vertex numbers with degree greater than one
A data frame with four elements; two edges (y1, z1) and
(y2, z2) will be removed, and two edges (y1, y2) and
(z1, z2) will be added between the four vertices.
