title: R CMD check doesn't detect my documentation
body: <p>When I run</p>
  
  <pre><code>R CMD build mypackage
  R CMD check mypackage_1.0.tar.gz
  </code></pre>
  
  <p>I'm getting this warning:</p>
  
  <pre><code>Undocumented code objects:
    ‘func1’ ‘func2’ 
  </code></pre>
  
  <p>However, my package structure has these functions documented in the <code>man</code> folder:</p>
  
  <pre><code>$ ls mypackage
  DESCRIPTION  man  NAMESPACE  R  README.md  tests
  </code></pre>
  
  <p>And these functions specifically have documentation:</p>
  
  <pre><code>$ ll mypackage/man
  -rw-r--r-- 1 user user  307 May 24 14:38 func1.Rd
  -rw-r--r-- 1 user user  307 May 29 15:38 func2.Rd
  </code></pre>
  
  <p>Which looks like so:</p>
  
  <pre><code>$ cat mypackage/man/func1.R
  \name{ func1 }
  \title{ Do func1}
  \description{
    This is well documented
    }
  </code></pre>
  
  <p>What am I missing to tell R this is where my documentation is?</p>
