%description
Turn irregular polygons (such as geographical regions) into regular or
hexagonal grids. This package enables the generation of regular (square)
and hexagonal grids through the package 'sp' and then assigns the content
of the existing polygons to the new grid using the Hungarian algorithm,
Kuhn (1955) (<doi:10.1007/978-3-540-68279-0_2>). This prevents the need
for manual generation of hexagonal grids or regular grids that are
supposed to reflect existing geography.
