[R-sig-Geo] Discrete Global Grids

[Richard Barnes]

I've recently released a package, dggridR, which interfaces with dggrid, 
and divides the entire surface of the Earth into equally-sized hexagonal 
bins without the need for intermediate projections.

This is useful for doing spatial statistics such as prevalence, 
presence-absence binning, and so on.

The package also contains utilities to aid in plotting the results.

Install with `install.packages('dggridR')` or find it on Github at 
https://github.com/r-barnes/dggridR/

Cheers,
Richard
