`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.

...

Passed to `make_star()`.

## Value

An igraph graph.

Other deterministic constructors: `graph_from_atlas()`, `graph_from_edgelist()`, `graph_from_literal()`, `make_()`, `make_chordal_ring()`, `make_empty_graph()`, `make_full_citation_graph()`, `make_full_graph()`, `make_graph()`, `make_lattice()`, `make_ring()`, `make_tree()`

## Examples

``````make_star(10, mode = "out")
#> IGRAPH 94aa8b4 D--- 10 9 -- Out-star
#> + attr: name (g/c), mode (g/c), center (g/n)
#> + edges from 94aa8b4:
#> [1] 1-> 2 1-> 3 1-> 4 1-> 5 1-> 6 1-> 7 1-> 8 1-> 9 1->10
make_star(5, mode = "undirected")
#> IGRAPH 31c0ce8 U--- 5 4 -- Star
#> + attr: name (g/c), mode (g/c), center (g/n)
#> + edges from 31c0ce8:
#> [1] 1--2 1--3 1--4 1--5
