Details

The m*ply functions are the plyr version of mapply, specialised according to the type of output they produce. These functions are just a convenient wrapper around a*ply with margins = 1 and .fun wrapped in splat.

This function combines the result into a list. If there are no results, then this function will return a list of length 0 (list()).
