R help - Jan 2010 - Possible to write text inside a bar of a barplot?

How can I write text inside a bar of a barplot? I tried using text(), but I
am only able to specify the numeric y-coordinate. The different columns of
my barplot correspond to factors and not numbers, so I don't know how to
access the horizontal positions of the bars. I tried fiddling with different
values of the "adj" argument, but this appears unreliable.

Background: I have created a barplot visualization where the bars represent
the size of different items (e.g. US state populations), and the sub-bars
represent the size of the different sub-components of each item (e.g.
counties). Picture: http://drop.io/hjcodjj/asset/capture-png

I would like to put in a label inside each sub-bar (e.g. indicating the name
of the county represented by that sub-bar).

p.s.: In case anyone finds this visualization useful I'll share my code
afterward, but just need to get the labeling working properly first.

Thanks for the replies! The answer is that barplot() returns the x
coordinates of the bars.
