How long is an object?

This is a function for the common task of testing the length of an object. It checks the length of an object in a non-generic way: base::length() methods are ignored.

Usage
has_length(x, n = NULL)
Arguments
x

A R object.

n

A specific length to test x with. If NULL, has_length() returns TRUE if x has length greater than zero, and FALSE otherwise.
