[R] reversing the scale on ggplot

[hadley wickham]

Hi Pedro,

Sorry for missing this email - the good news is that in the next
version of ggplot (hopefully coming out in the next few days), you'll
be able to do:

qplot(x, y, data=plotdata) + scale_x_reverse()
qplot(x, y, data=plotdata) + scale_y_reverse()

to get reversed scales
