title: Plot table function objects with ggplot?
body: <p>I've got this data:</p>
  
  <pre><code>table(main$Sex1,main$District)
  
          Bahawalnagar Barkhan Chiniot  Faisalabad Ghotki 
  Female    37           16       26       97         46          
  Male      25           19       15       20         25 
  </code></pre>
  
  <p>I can plot it with base R       </p>
  
  <pre><code>barplot(table(main$Sex1,main$District))
  </code></pre>
  
  <p>So my question is, how can I do this with ggplot2? Thanks</p>
