  I have looked at many examples and tried many different combinations of doing this, but with no luck. I have something like this:

plot(1:10, xaxt = "n")
axis(1, xaxp=c(2, 9, 7))

but, what I need is to have different labels for axis-4 than those for axis-2 (the vertical axes) that is, rather than 2,4,6,8,10 for both the left and right vertical axes, I need A,B,C,D,E on the right but at the same tick locations as those on the left. I have tried using at=1:5, labels=c(), but either nothing happens or I overwrite axis-4 at different tick locations; in any case, not what I need. How can I do this?
