plyr (version 1.5.2)

l_ply: Split list, apply function, and discard results.

Description

Split list, apply function, and discard results. For each element of a list, apply function and discard results

Usage

l_ply(.data, .fun, ..., .progress="none", .print=FALSE)

Arguments

.data
list to be processed
.fun
function to apply to each piece
...
other arguments passed on to .fun
.progress
name of the progress bar to use, see create_progress_bar
.print
automatically print each result? (default: FALSE)

Details

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.
