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.
