#There are a lot of examples for barplot if you just type
# i altered one slightly to put the values on top of each bar
mp <- barplot(VADeaths) # default
#tot <- colMeans(VADeaths) #changed this line
tot = colSums(VADeaths) #wether you need max, min, mean , colSums
will depend on your data
text(mp, tot + 4, format(tot), xpd = TRUE, col = "blue")
#you should be able to get it from here
