layout.star: Generate coordinates to place the vertices of a graph in a star-shape

Description

A simple layout generator, that places one vertex in the center of a circle and the rest of the vertices equidistantly on the perimeter.

Usage

layout.star(graph, center = V(graph)[1], order = NULL)

Arguments

graph
The graph to layout.
center
The id of the vertex to put in the center. By default it is the first vertex.
order
Numeric vector, the order of the vertices along the perimeter. The default ordering is given by the vertex ids.

Value

  • A matrix with two columns and as many rows as the number of vertices in the input graph.

concept

Graph layout

Details

It is possible to choose the vertex that will be in the center, and the order of the vertices can be also given.
