Check numeric objects:
is_odd(x)is_even(x)
is_positive(x, strict = FALSE)
is_whole(x, tolerance = .Machine$double.eps^0.5)
is_binary(x)
A numeric
object to be tested.
A logical
scalar: should missing values
(including NaN
) be omitted?
A numeric
scalar giving the
tolerance to check within.
A logical
vector.

and is_even
check if a number is odd or even,
respectively.
is_positive
checks if an object contains only (strictly) positive
