erdos.renyi.game | R Documentation |
Simple random graph model, specifying the edge count either precisely
(G(n,m)
model) or on average through a connection probability
(G(n,p)
model).
erdos.renyi.game(
n,
p.or.m,
type = c("gnp", "gnm"),
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 ( |
type |
The type of the random graph to create, either |
directed |
Logical, whether the graph will be directed, defaults to
|
loops |
Logical, whether to add loop edges, defaults to |
In G(n,m)
graphs, there are precisely m
edges.
In G(n,p)
graphs, all vertex pairs are connected with the same
probability p
.
random.graph.game()
is an alias to this function.
A graph object.
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.
