dg_process_polydata

Polygons generated by dggrid. These will be converted.

polydata

If TRUE, return a data frame suitable for ggplot plotting.
If FALSE, return an SpatialPolygons

frame

Cells which cross -180/180 degrees can present 
difficulties for plotting. Setting this TRUE will result in
cells with components in both hemispheres to be mapped
entirely to positive degrees (the Eastern hemisphere). As a
result, such cells will have components in the range
[180,360). Only used when <code>frame=TRUE</code>.

Convert data from internal dggrid functions into something
 useful: an sp object or a data frame

Spatial analyses involving binning require that every bin have the same area, but this is impossible using a rectangular grid laid over the Earth or over any projection of the Earth. Discrete global grids use hexagons, triangles, and diamonds to overcome this issue, overlaying the Earth with equally-sized bins. This package provides utilities for working with discrete global grids, along with utilities to aid in plotting such data.
