`sapply()` implies that you expect the result to be _s_implified, which implies that all your elements are the same length. Sounds like you want to use `lapply()` instead, to signal that it will *not* be simplified, even if by chance the elements are the same length.

Therefore, vapply may not be of use for me in those cases. Is there any solution for it? Or shall I ignore the Note?
