Akki,
1. Have a look at the result from a barplot() call.
>From the help:
A numeric vector (or matrix, when beside = TRUE), say mp, giving the
coordinates of all the bar midpoints drawn, useful for adding to the
graph.
2. Have a look at the text() function that will annotate plots!
So, try this for starters:
my.values=1:5
x <- barplot(my.values, ylim=c(0,7))
text(x, 0.4+my.values, "wibble")
Hope this helps,
Best wishes,
Mark
