[R] Fwd: how to add value on the bar ploted by barplot()

[David Winsemius]

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.
