erdos.renyi.game: Generate random graphs according to the Erdős-Rényi model

In igraph: Network Analysis and Visualization

Generate random graphs according to the Erdős-Rényi model

Description

Since igraph version 0.8.0, both erdos.renyi.game() and random.graph.game() are deprecated, and sample_gnp() and sample_gnm() should be used instead. See these for more details.

random.graph.game() is an (also deprecated) alias to this function.

Usage

erdos.renyi.game(
  n,
  p.or.m,
  type = c("gnp", "gnm"),
  directed = FALSE,
  loops = FALSE
)

Arguments

n	The number of vertices in the graph.
p.or.m	Either the probability for drawing an edge between two arbitrary vertices (G(n,p) graph), or the number of edges in the graph (for G(n,m) graphs).
type	The type of the random graph to create, either gnp() (G(n,p) graph) or gnm() (G(n,m) graph).
directed	Logical, whether the graph will be directed, defaults to FALSE.
loops	Logical, whether to add loop edges, defaults to FALSE.

Value

A graph object.
