Try this:

plot(xx, yy, type="l", xlim=rev(range(xx)))

Subject: [R] Putting x-axis in opposite order

Hi all, please consider this plot:


xx <- seq(4, 0.01, by = -0.04)

yy <- rnorm(xx)

plot(xx, yy, type="l")


Here you see my original 'xx' was in decreasing order, however R puts it in
the increasing order. I understand that in any plot x and y axis grow is
increasing order, however I am wondering whether I can manipulate this to
suit my above particular problem, so that number displayed in x-axis would
be in the given order.
