Hi All,
I'd like to understand the reason why stopifnot(logical(0) == x) doesn't
(never?) throw an exception, at least in these cases:
stopifnot(logical(0) == 1)
stopifnot(logical(0) == TRUE)
stopifnot(logical(0) == FALSE)
My understanding is that logical(0) is an empty set, so I would expect the
above tests to fail.
(I got bitten by this in a piece of code where "x" happened to be
logical(0) and stopifnot didn't catch it)
Thanks!
Dario
