%description
Extends 'data.table' join functionality, lets it work with any data frame
class, and provides a familiar 'x'/'y'-style interface, enabling broad use
across R. Offers NA-safe matching by default, on-the-fly column selection,
multiple match-handling on both sides, 'x' or 'y' row order, and a row
origin indicator. Performs inner, left, right, full, semi- and anti-joins
with equality and inequality conditions, plus cross joins. Specific
support for 'data.table', (grouped) tibble, and 'sf'/'sfc' objects and
their attributes; returns a plain data frame otherwise. Avoids
data-copying of inputs and outputs. Allows displaying the 'data.table'
code instead of (or as well as) executing it.
