Hey, the solution happens to be only partiall... If the values are not real 
numbers, and have a lot of digits after the dot, the graph might become 
unreadable... 

see this

vals <- 
c(1,1.1236886,4.77554676,5.3345245,1,1.1236886,4.77554676,5.3345245,5.5345245,5.4345245,1.1236886,4.77554676,5.3345245,1.1236886,4.77554676,5.3345245) 
names(vals) <- LETTERS[1:16] 
mp <- barplot(vals, ylim = c(0, 6)) 
text(mp, vals, labels = vals, pos = 3) 

Is there any way to round up those numbers?

I tried using 
options(digits=2)
, and it does change the display of a table, but it does not influence the 
barplot...
