title: Can't fill by character in ggplot2
body: <p>I'm trying to construct a boxplot figure where one layer is color coding the boxes based on +/- Oxygen, but I keep receiving the following error: &quot;Error in UseMethod(&quot;fill_&quot;) :
  no applicable method for 'fill_' applied to an object of class &quot;character&quot;.</p>
  <p>This doesn't make sense to me. I've used characters as input before, why isn't it working this time?</p>
  <p>The following is the code I attempted:</p>
  <pre><code>stackoverflow_plot &lt;- stackoverflow %&gt;% na.omit() %&gt;% ggplot(., mapping = aes(Oxygen, concentration)) + geom_boxplot(aes(fill(Oxygen)), alpha = 0.5, outlier.shape = NA) + facet_wrap('Drug', scales = 'free')
  </code></pre>
  <p>And this is my dataframe:</p>
