That book tries rather hard to show only the basic procedure and
not to do fancy things, so this is not explicitly covered in there. It
does describe barplot() and text(), though. (Odd, BTW, www.springer.de

Also, try 

par(ask=T); example(barplot)

The fourth example is fairly close to what you want to do (colSums
instead of colMeans should place the numbers at the end of the
columns).
