The post-processing action if multiple files are supplied. This parameter will be ignored if only a single file is supplied.

'none' (default) to leave the resulted list as a list of elements corresponding to elements in file vector.

'merge' to merge the list elements iteratively, the later lists always modify the former ones through modifyList.

'ungroup' to ungroup the list elements, especially when each file is a page of elements with identical structure.
