sample_gnpR Documentation

Generate random graphs according to the G(n,p) Erdős-Rényi model

Description

This model is very simple, every possible edge is created with the same constant probability.

Usage

sample_gnp(n, p, directed = FALSE, loops = FALSE)

gnp(...)

Arguments

n

The number of vertices in the graph.

p

The probability for drawing an edge between two arbitrary vertices (G(n,p) graph).

directed

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

loops

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

...

Passed to sample_gnp().

Details

The graph has ‘n’ vertices and for each edge the probability that it is present in the graph is ‘p’.

Value

A graph object.
