[R] Proportional axes

[Agustin Lobo]

Hi!

If I'm plotting 2 variables with the same units
(i.e. wing length of 2 species), how can I force that X
and Y axes have the same size for length unit? For example, if
X ranges from 0 to 10 and Y ranges from 10 to 30, I want
Y axis to be twice as long as X axis. I know I can just
put xlim and ylim from 0 to 30, i.e.,
plot(runif(10,0,10),runif(10,10,30),xlim=c(0,30),ylim=c(0,30))

but this is a waste of space.

Thanks
