This layout places vertices on a rectangulat grid, in two or three
dimensions.
Usage
layout_on_grid(graph, width = 0, height = 0, dim = 2)
on_grid(...)
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, then for 2d layouts 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, it will be the cube root
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.
dim
Two or three. Whether to make 2d or a 3d layout.
...
Passed to layout_on_grid.
Value
A two-column or three-column matrix.
Details
The function places 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 function.
