This vignette discusses some design decisions made in this package and the rationale behind them.
A very early prototype of this package used this approach of taking
the path of an entire folder. But we quickly noticed it severely lacked
flexibility. For example, some users may have subfolders in their main
folder, and may want or not to parse files within these subfolders.
Alternatively, they may want to exclude some files in the folder based
on a certain pattern in the file name. Handling this in
{xlcutter} would force us to add extra arguments (such as
recursive, pattern, etc.), that we would to
pass to list.files(). Or users may even want to pass
individual files scattered across many folders.
Passing a list of files rather than an entire folder sacrifices a tiny amount of ease of use for a large increase in flexibility.
