This is the trivial modification to the example on the help page that
I was thinking of.
#the example code
mp <- barplot(VADeaths) # default
tot <- colMeans(VADeaths)
text(mp, tot + 3, format(tot), xpd = TRUE, col = "blue")
#the modification
tot <- colSums(VADeaths)
text(mp, tot + 3, format(tot), xpd = TRUE, col = "red")
You can learn quite a bit by running the examples on graphics pages.

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}
and the axis label is too big, anyone know how to change their
font ,
thanks
?barplot # again ... barplots help page seems quite clear
cex.names = 0.5 # or a number less than one of your choice
