duckdf: SQL for Dataframes, but with Ducks
An SQL interface for R dataframes built on the DuckDB embedded analytical database. Dataframes are registered directly with an in-process DuckDB instance and queried with standard SQL, so analyses can join, filter, aggregate and reshape R objects with SQL while results are returned as dataframes, without copying data to an external database server. The package wraps the 'duckdb' R package with a DBI-compliant connection and provides a small, checked surface for the common register-query-unnregister workflow. The underlying engine and its vectorised execution model are described in Raasveldt and Mühleisen (2019) <doi:10.1145/3299869.3320212>.
