watts.strogatz.game {igraph} | R Documentation |
Generate a graph according to the Watts-Strogatz network model.
watts.strogatz.game(dim, size, nei, p)
dim |
Integer constant, the dimension of the starting lattice. |
size |
Integer constant, the size of the lattice along each dimension. |
nei |
Integer constant, the neighborhood within which the vertices of the lattice will be connected. |
p |
Real constant between zero and one, the rewiring probability. |
First a lattice is created with the given dim
, size
and
nei
arguments. Then the edges of the lattice are rewired
uniformly randomly with probability p
.
Note that this function might create graphs with loops and/or multiple
edges. You can use simplify
to get rid of these.
A graph object.
