Spherical Geometry Operators Using the S2 Geometry Library
Provides R bindings for Google's s2 library for geometric calculations on
the sphere. High-performance constructors and exporters provide high compatibility
with existing spatial packages, transformers construct new geometries from existing
geometries, predicates provide a means to select geometries based on spatial
relationships, and accessors extract information about geometries.
This version of s2 can be found in the following snapshots:
