In igraph: Network Analysis and Visualization

Create a star graph, a tree with n vertices and n - 1 leaves

Description

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.
