uncount_dt

Duplicating rows according to a weighting variable.
 This is the opposite operation of `count_dt`.
 Analogous to `tidyr::uncount`.

A toolkit of tidy data manipulation verbs with 'data.table' as the backend.
Combining the merits of syntax elegance from 'dplyr' and computing performance from 'data.table',
'tidyfst' intends to provide users with state-of-the-art data manipulation tools with least pain.
This package is an extension of 'data.table'. While enjoying a tidy syntax,
it also wraps combinations of efficient functions to facilitate frequently-used data operations.
