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.
