Depending on what you really mean, possibly:

?barplot
?text  # there _is_ a worked example on the barplot help page.
        # true, it does put the labels above the bars, but the  
modification would be trivial.
# or
?addtable2plot {in package plotrix}

?barplot   # again ...  barplots help page seems quite clear

       cex.names = 0.5    # or a number less than one of your choice
