erdos.renyi.game {igraph} | R Documentation |
This model is very simple, every possible edge is created with the same constant probability.
erdos.renyi.game(n, p.or.m, type="gnp", directed = FALSE, loops = FALSE, ...)
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. |
... |
Additional arguments, ignored. |
In G(n,p) graphs, the graph has ‘n’ vertices and for each edge the probability that it is present in the graph is ‘p’.
In G(n,m) graphs, the graph has ‘n’ vertices and ‘m’
edges, and the ‘m’ edges are chosen uniformly randomly from the
set of all possible edges. This set includes loop edges as well if the
loops
parameter is TRUE.
random.graph.game
is an alias to this function.
A graph object.
