This is generally pretty easy with text() at least if you are using  
base graphics. If it is not clear after reading the help page then  
post an examply with whatever barchart function you have chosen to  
use. If it's the lattice barchart there is an ltext example  
immediately before the barchart example that quickly can be grafted  
into the barchart code.
