vec2mat: Auxiliary function, produces matrix from vector

In ghypernet: Fit and Simulate Generalised Hypergeometric Ensembles of Graphs

Description

The number of elements of vec are the number of non-zero elements in the adjacency matrix. It performs the opposite operation of 'mat2vec.ix'.

Usage

vec2mat(vec, directed, selfloops, n)

Arguments

vec	vector to be put in matrix form
directed	a boolean argument specifying whether object is directed or not.
selfloops	a boolean argument specifying whether the model should incorporate selfloops.
n	vector. if length(n)==1, n is the number of vertices. If length(n)==3 first element is number of vertices, second and third elements are number of vertices for row and column of bipartite matrix.

Value

matrix nxn generated from vector.

Examples

data('adj_karate')
ix <- mat2vec.ix(adj_karate, FALSE, FALSE)
vec <- adj_karate[ix]
vec2mat(vec, FALSE, FALSE, nrow(adj_karate))
