Not with the standard R graphics - think of the graphics window as a piece of paper and if you draw anything on it you have done so in permanent ink. If something needs changing you need a new sheet of paper and have to redraw the lot. Most people I know write their code in some text editor and send (or copy paste) it into R. It is an easy matter to edit one or two bits of your code to tweak the display and re-plot... I think you can modify lattice graphics objects and just plot (print really) them again - but again you are really redrawing the whole plot from scratch. IIRC grid might be able to do some of what you are looking for. > > Oh, and a quick cosmetic query---I notice that the axes when created are > spaced apart somewhat so the axis lines do not meet at the plot origin. > Is there a way to alter this so that the outline of the box, and the > extreme values of the axis, match up? > Look at ?par and xaxs and yaxs.
