[R] How to get correct proportions/bounding box for latex figure?

[context grey]

That's approximately right, but the individual
scatterplots
are slightly stretched horizontally.   

Is there not any way to have the plots have true 1:1
aspect ratio
(given that the range of the data is the same on both
axes)
and still get a bounding box?.   And, without getting
out
a ruler and manually calculating width/height values?

(I'm guessing you arrived at width=12,height=4 just
by "eyeballing" it.?)
