Dear R-users, I am trying to produce (standard and trellis) scatterplots which use the same range of the x and y axes. In addition, I would like the plots to be physically square. Is there one or more specific argument(s) to plot and xyplot what would do that? I have looked at various combinations of asp and pin value, but could not get what I wanted.. Thank you in advance for your help Sebastien

I would typically need to set asp=0.85 to get what looked to ba a square plot. Suggest reading the documentation for plot.window() as a start. -- David Winsemius, MD Heritage Laboratories West Hartford, CT
Hi Sebastien, take a look at the par(pty='s') argument. Maybe its can solve your issue. Best wishes.
