n_cells

n_cells,Quadtree-method

Returns the number of nodes/cells in the quadtree.

Provides functionality for working with raster-like quadtrees
(also called “region quadtrees”), which allow for variable-sized
cells. The package allows for flexibility in the quadtree creation
process.  Several functions defining how to split and aggregate cells
are provided, and custom functions can be written for both of these
processes. In addition, quadtrees can be created using other quadtrees
as “templates”, so that the new quadtree's structure is identical to
the template quadtree. The package also includes functionality for
modifying quadtrees, querying values, saving quadtrees to a file, and
calculating least-cost paths using the quadtree as a resistance
surface.
