Given a set of logical vectors, is at least one of the values true?
zero or more logical vectors. Other objects of zero length are ignored, and the rest are coerced to logical ignoring any class.

This is a generic function: methods can be defined for it

For this to work properly, the arguments

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