Are you using tkrplot? If so, I have tried implementing ways to allow dragging the corner of a tk window with a plot in it and have it automatically resize, but I have found it to be quite difficult. So my two solutions are either 1. Just use the regular R graphics device (not tkrplot), or 2. Have a pull-down (or pop-up) menu from your tkrplot window which allows the user to enter horizontal and vertical scaling factors for the plot (in a dialog box) so they can resize it, even if it's not by dragging the corner of the plot window. Or even have the entry boxes for horizontal and vertical scaling factors on the same tk window as the plot (beside the plot or above it or whatever), so that the user can instantly see how to resize the plot, e.g. by replacing a horizontal scaling factor of 1.5 by 1.6. A bit ugly? Yes. But I've never found a really nice solution to this problem. If you are using Windows, then in my opinion, using the regular R graphics device in an R-Tcl/Tk application is quite ugly if you are running R in MDI (Multiple Document Interface) mode. BUT it looks fine if you are running R in SDI (Single Document Interface) mode.
