 Dear useRs,
 
 I'd like to produce some scatter plots where N units on the X axis are
 equal to N units on the Y axis (as measured with a ruler, on screen or
 paper). This approach
   x - sample(10:200,40) ; y - sample(20:100,40)
   windows(width=max(x),height=max(y))
   plot(x,y)
 is better than plot(x,y) but doesn't solve the problem because of the
 other parameters (margins etc). Is there an easy, official way of
 sizing the axes to the same scale, one that would also work with
 multiple scatter plots being sent to the same pdf() - plus perhaps
 layout() or par(mfrow())?
 
 Thank you,
 b.
