  At this time, you have to do something like

x <- rnorm(100)
y <- rnorm(100)
plot(max(x)-x,max(y)-y,axes=FALSE)
xlabvals <- pretty(x,5)
ylabvals <- pretty(y,5)
axis(side=1,at=max(x)-xlabvals,labels=xlabvals)
axis(side=2,at=max(y)-ylabvals,labels=ylabvals)

  I think it's time to put this one in the FAQ ... (although, again, I
don't know if I would have found it just searching the archives if I
hadn't remembered that it was there in the first place).

If I understand this right, you want to reverse the direction of the axes.
This is a bug which seems to have crept in at some point and hung around
rather longer than it should have.  In the development version you can
now do the following:

	x <- rnorm(100)
	y <- rnorm(100)
	plot(x, y, xlim=rev(range(x)), ylim=rev(range(y)))

and get the result you expect.
