Dear R users, is there a way to tell R where to draw the windows where the plots are drawn ? I always get that window on the right of my screen, where it interferes with my Xemacs + ESS window where I'm writing lines. Of course I can move it manually, but I would like to have it permanently on the right, rather than on the left. Thanks for any advice Ottorino Ubuntu 7.10 Xemacs 21.4
