Warning: “Variables with usage in documentation object ‘FANG’ but not in code:” : <p>On R-devel (>3.6.1 at the time), a new warning has popped up in my package when running R CMD Check that looks like:</p>

<pre><code>“Variables with usage in documentation object ‘FANG’ but not in code:”
'FANG'
</code></pre>

<p>FANG is a data set that I include in my package.</p>
