[R] Reversing x-axis

[Kjetil Kjernsmo]

Dear all,

I'm making a system to create a star-chart, and I have encountered one of
the intuitive and clearly thoughtful conventions that are so common in
astronomy :-J... Well, the point being, I have to reverse the x-axis.
I figured, I might just set xlim=rev(range(x)). Do e.g.
> x <- 0:5
> y <- (0:5)^3
> plot(x, y)
> plot(x, y, xlim=rev(range(x)))
The problem is that here (R-1.1.1.1, osf4.0e), the numbers on the axis
doesn't come out right when I do this. Only the last tick mark has a
number, namely min(x). Is this a bug or a feature?

Anybody have a good workaround? I've tried (for this example)
axis(1, rev(x), rev(x))

Best,

Kjetil
