All plyr functions use the same split-apply-combine strategy: they split the
input into simpler pieces, apply .fun
to each piece, and then combine
the pieces into a single data structure. This function splits lists by
elements and discards the output. This is useful for functions that you are
calling purely for their side effects like display plots and saving output.
