r-cran-s2 binary package in Ubuntu Oracular armhf

 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.
