incidence.from.vector {incidentally}

Generates an incidence matrix with given row and column marginal sums

Description

incidence.from.vector generates a random incidence matrix with given row and column sums

Usage

incidence.from.vector(R, C, class = "matrix", narrative = FALSE)

Arguments

R

numeric vector: row marginal sums

C

numeric vector: column marginal sums

class

string: the class of the returned backbone graph, one of c("matrix", "Matrix", "igraph").

narrative

boolean: TRUE if suggested text & citations should be displayed.

Value

An incidence matrix of class matrix or Matrix, or a bipartite graph of class igraph.
