Description

Place vertices on a circle, in the order of their vertex ids.

Usage

layout_in_circle(graph, order = V(graph))

in_circle(...)

Arguments

graph	The input graph.
order	The vertices to place on the circle, in the order of their desired placement. Vertices that are not included here will be placed at (0,0).
...	Passed to layout_in_circle.

Details

If you want to order the vertices differently, then permute them using the permute function.

Value

A numeric matrix with two columns, and one row for each vertex.
