Barplots with column names
<p>I have this dataset :</p>

<pre><code> dat&lt;-read.table(text = "pl     Freq
             Abid     23
             Berl     54
             Cara     54
             Daka     10",header=T)
</code></pre>

<p>I am trying to have an histogram with the name of each columns (under the columns (i.e. "pl" informations)  and the columns sorted in decreasing order...
I tried a lot of ordering method, but :</p>

<pre><code> barplot(dat$freq)
</code></pre>

<p>Seems to not be the good way...</p>

<p>I you have any idea that would be helpfull !</p>

<p>Cheers,</p>

<p>R.</p>
