See asp in help(plot.default), though this doesn't seem to change the aspect
ratio of the box (which you can probably do with par).
An alternative is to use xyplot in the lattice library:
xyplot(y ~ x, type = "l", aspect = 1/5)
(This will make the aspect ratio of the bounding box 1/5 and not the actual
scales, but you can control that by further specifying xlim and ylim.)
Hope that helps,
