Simple grid layout

This layout places vertices on a rectangulat grid, in two or three dimensions.

Keywords
graphs
Usage
layout.grid (graph, width = 0)
layout.grid.3d (graph, width = 0, height = 0)
Arguments
graph
The input graph.
width
The number of vertices in a single row of the grid. If this is zero or negative for layout.grid, then the width of the grid will be the square root of the number of vertices in the graph, rounded up to the next integer. Similarly,
height
The number of vertices in a single column of the grid, for three dimensional layouts. If this is zero or negative, then it is determinted automatically.
Details

These functions place the vertices on a simple rectangular grid, one after the other. If you want to change the order of the vertices, then see the permute.vertices function.

Value

  • A two-column matrix for layout.grid, a three-column matrix for layout.grid.3d.
