star() creates a star graph, in this every single vertex is
connected to the center vertex and nobody else.
Usage
make_star(n, mode = c("in", "out", "mutual", "undirected"), center = 1)
star(...)Arguments
- n
Number of vertices.
- mode
It defines the direction of the edges,
in: the edges point to the center,out: the edges point from the center,mutual: a directed star is created with mutual edges,undirected: the edges are undirected.- center
ID of the center vertex.
- ...

make_star().
