Patient: "Doctor, when I move my arm like this it hurts." Doctor: "Well...stop moving your arm like that." ;-) I think that unlike your lattice example below, the X11 device is "elastic" on a resize. I do not see a par() setting that alters that behavior. For some reason, I think that under Windows there was a setting for the default Windows graphics device relative to resizing, but that my be the result of a TIA and not the representation of reality...I hate it when that happens. :-) > If I set par(pty='s') I can have a square plot floating inside a > graphics window of any shape, I'd like to be able to plot something > specifying ylim and asp and get a rectangular plot with a fixed aspect > ratio floating around inside a resizable graphics device.... > > The 'aspect' ratio of xyplot (lattice package) lets you specify the > aspect ratio of the plot (not relating to the data, ie aspect=1 draws a > square plot whatever the ratio of X and Y range).

I am not sure what might be a "best" approach. I'll think about it. If I come up with anything, I'll let you know. I guess that one underlying consideration I might think about here is, where is your final output going. If to a PS file for printing or inclusion in a LaTeX document, I would focus on how the plot looks there, especially when trying to compare it to X11 output.
