layout.star {igraph} | R Documentation |
A simple layout generator, that places one vertex in the center of a circle and the rest of the vertices equidistantly on the perimeter.
layout.star(graph, center = V(graph)[0], order = NULL)
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. |
It is possible to choose the vertex that will be in the center, and the order of the vertices can be also given.
A matrix with two columns and as many rows as the number of vertices in the input graph.
