Generate random signed graphs according to the G(n,p) Erdos-Renyi model

Usage

sample_gnp_signed(n, p, p_neg, directed = FALSE, loops = FALSE)

Arguments

n

The number of vertices in the graph.

p

The probability for drawing an edge between two arbitrary vertices.

p_neg

The probability of a drawn edge to be a negative tie

directed

logical, whether the graph will be directed. defaults to FALSE.

loops

logical, whether to add loop edges, defaults to FALSE.

Value

a signed igraph graph object
