How to plot a one column data frame with ggplot?
<p>I have a data frame like this:</p>

<pre><code> __________
|   | sums |
|---+------|
| a | 122  |
|---+------|
| b | 23   |
|---+------|
| c | 321  |
|__________|
</code></pre>

<p>*Notice "a","b" and "c" are row names.</p>

<p>I would like to see a plot like this:</p>

<pre><code>                    ___
300 -|             |   |
200 -|  ___        |   |
100 -| |   |  ___  |   |
  0 -|_|___|_|___|_|___|______
         a     b     c
</code></pre>

<p>How can I accomplish that?</p>
