title: R Draw All Axis Labels (Prevent Some From Being Skipped)
body: <p>When I manually add the following labels with (<code>axis(1, at=1:27, labels=labs[0:27])</code>):</p>
  
  <pre><code>&gt; labs[0:27]
   [1] "0\n9.3%"  "1\n7.6%"  "2\n5.6%"  "3\n5.1%"  "4\n5.7%"  "5\n6.5%"  "6\n7.3%"  "7\n7.6%"  "8\n7.5%"  "9\n7%"    "10\n6.2%" "11\n5.2%"
  [13] "12\n4.2%" ........
  </code></pre>
  
  <p>I get the following:</p>
