"any" function gives warning message

I was typing some code in R and noticed that 

> any(range(2.0,3.0))

gave me the following:

Warning message:
In any(range(2, 3)) : coercing argument of type 'double' to logical

I looked up the help function by typing ? any and got the following:

Coercion of types other than integer (raw, double, complex, character, list) gives a warning as this is often unintentional.

So I typed any(range(2,3)) and still got the same warning. Am I doing something wrong?

Why are you using the function like that? As the documentation says, a coercion happens because any is called on logical values (TRUE, FALSE). It makes little sense on other values.

As for why you’re still getting the error: in R, 2 and 3 are numerics, not integers. You could use any(range(2L, 3L)) but this isn’t really any more meaningful. In fact, R should warn here as well.
