Package: duckspatial 1.2.0

Adrián Cidre González

duckspatial: R Interface to 'DuckDB' Database with Spatial Extension

Fast and memory-efficient functions to analyze and manipulate large spatial datasets. It leverages the fast analytical capabilities of ‘DuckDB’ and its spatial extension (see <https://duckdb.org/docs/stable/core_extensions/spatial/overview>) while maintaining compatibility with R’s spatial data ecosystem to work with spatial vector data.
