a5_grid_disk: Cells within k hops of a cell
In a5R: 'A5' Discrete Global Grid System
a5_grid_disk R Documentation
Cells within k hops of a cell
Description
Returns all cells reachable within k edge hops of a centre cell,
including the centre cell itself.
Usage
a5_grid_disk(cell, k, vertex = FALSE)
Arguments
cell
A single a5_cell value.
k
Integer scalar, number of hops.
vertex
Logical scalar. If FALSE (default), only edge-sharing
neighbours (4-connected) are traversed. If TRUE, vertex-sharing
neighbours are included (8-connected).
Value
A compacted a5_cell vector.
See Also
a5_spherical_cap() for distance-based selection.
Examples
cell <- a5_lonlat_to_cell(-3.19, 55.95, resolution = 8)
a5_grid_disk(cell, k = 1)
