Package: Rducks 0.1.1.9000

Rducks: Register R User-Defined Functions in DuckDB

R package and 'DuckDB' extension bridge for registering R functions as 'DuckDB' user-defined functions (UDFs). The package is designed around a loaded 'DuckDB' extension, declarative type descriptors, direct native vector marshalling, and explicit execution discipline for safe interaction with R from 'DuckDB' execution. The inter-process worker transport uses vendored 'NNG' (nanomsg next generation).
