[R] (Small) problem with barchart

I have a small problem when using barchart. I have the following data:

   letters a

6        f 18
1        a 15
10       j 12
9        i 12
4        d  9
5        e  6

The data is from a survey and summaries the alternatives selected in one question. The idea is to have a bar chart illustrating the count of each selection in descending order. The data frame is already ordered in descending order. Thus, the chart _should_ look like this:

f |xxxxxxxxxxxxxxxxxx
a |xxxxxxxxxxxxxxx
j |xxxxxxxxxxxx
i |xxxxxxxxxxxx

d |xxxxxxxxx
e |xxxxxx

But if I use the command:
> barchart(DATA[[2]] ~ DATA[[1]])

The bars are displayed in alphabetical order.

How could I get the graph I would like to have?

Thanks in advance & regards,
