The goal of dd is to provide documentation for DuckDB’s functions, and later also an easy way to test them. It is meant to be used in conjunction with duckplyr and duckdb.

These pages document the functions of DuckDB 1.5.5.

You can install the development version of dd like so:

pak::pak("cynkra/dd")

library(dd)
dd$acos
#> function(x = DOUBLE) {
#>   stop("DuckDB function acos() is not available in R.")
#> }
#> <bytecode: 0xdeadbeef>
#> <environment: namespace:dd>

help(acos, package = "dd")
