datasets

Provides a minimal R and C++ API for parsing
well-known binary and well-known text representation of
geometries to and from R-native formats.
Well-known binary is compact
and fast to parse; well-known text is human-readable
and is useful for writing tests. These formats are
useful in R only if the information they contain can be
accessed in R, for which high-performance functions
are provided here.
