maditr: Fast Data Aggregation, Modification, and Filtering with Pipes
Provides pipe-style interface for 'data.table'. Package preserves all 'data.table' features without
significant impact on performance. 'let' and 'take' functions are simplified interfaces for most common data
manipulation tasks. For example, you can write 'take(mtcars, mean(mpg), by = am)' for aggregation or
'let(mtcars, hp_wt = hp/wt, hp_wt_mpg = hp_wt/mpg)' for modification. Use 'take_if/let_if' for conditional
aggregation/modification. Additionally there are some conveniences such as automatic 'data.frame'
conversion to 'data.table'.
