%description
Tidy syntax for 'data.table', using modification by reference whenever
possible. This toolkit is designed for big data analysis in
high-performance desktop or laptop computers. The syntax of the package is
similar or identical to 'tidyverse'. It is user friendly, memory efficient
and time saving. For more information, check its ancestor package
'tidyfst'.
