isFALSE deprecated?

Hi, Thanks for the package. It seems that the dev version uses 'isFALSE', and that this function is now deprecated. Defining
isFALSE <- function(x) {is.logical(x) && length(x) == 1 && !is.na(x) && !x }
seems to solve the issue, at least temporarily.

Can you provide a reproducible example of when you get a message about isFALSE() being deprecated? To my knowledge, it is not.

At least, isFALSE does not seem to be defined in my version of R (3.4.4).

Oh, apparently isFALSE() is new to R 3.5.0. That's not nearly a good enough reason to require R 3.5, so I'll define it for now. Thanks!
