geodist_benchmark

Benchmark errors for different geodist measures

Dependency-free, ultra fast calculation of geodesic
distances. Includes the reference nanometre-accuracy geodesic
distances of Karney (2013) <doi:10.1007/s00190-012-0578-z>, as used by
the 'sf' package, as well as Haversine and Vincenty distances. Default
distance measure is the "Mapbox cheap ruler" which is generally more
accurate than Haversine or Vincenty for distances out to a few hundred
kilometres, and is considerably faster. The main function accepts one
or two inputs in almost any generic rectangular form, and returns
either matrices of pairwise distances, or vectors of sequential
distances.
