Random Bernoulli graph

rbernoulli(n, p = 0.5)

Arguments

n	Integer vector. Size of the graph. If `length(n) > 1`, then it will a list of random graphs.
p	Probability of a tie. This may be either a scalar, or a vector of the same length of `n`.

Value

If n is a single number, a square matrix of size n with zeros in the diagonal. Otherwise it returns a list of length(n) square matrices of sizes equal to those specified in n.
