title: Barplot in ggplot
body: <p>I'm having problems making a barplot using <em>ggplot</em>.</p>
  <p>I tried different combinations of <em>qplot</em> and <em>gplot</em>, but I either get a histogram, or it swaps my bars or it decides to use log-scaling.</p>
  <p>Using the ordinary plot functions. I would do it like:</p>
  <pre><code>d &lt;- 1/(10:1)
  names(d) &lt;- paste(&quot;id&quot;, 1:10)
  barplot(d)
  </code></pre>
