You also need to set the xlim and ylim parameters, because that also
defaults to (-1,1).

No, that's not possible. Rescale the layout for yourself, and then set
these limits in xlim and ylim.
Btw. if you include code this way, that is somewhat a pain to try,
because the > prompt makes it impossible to copy and paste. It is best
to include some code that we can just copy and paste into R, without
needing to edit it in emacs.
