Hello, First, my thanks to the R developers; it is a wonderful tool and supports my development and production activities in many helpful ways. My problem is as follows: I want to make long (~ 20-30 feet) plots on a HP 755 (36" color roll plotter) using the R postscript command. I have tried paper="special" with appropriate width and height, and everything seems ok from the postscript side. But the plot gets truncated to whatever -o PageSize I specify (which, of course, makes sense). But using -o w2592 (36" roll unlimited) truncates to letter. Enough words: here is what I am using now. postscript("|lpr -P hp755 -o PageSize=ARCHE", paper="special",width=ww,length=ll) This limits me to 48 inches (ARCHE=36*48). In summary, does anyone know the correct choice of parameters to get a roll plot without a predefined limit. I did set ps.options(paper)="default" instead of "letter" and I am using R 1.8.1 on Linux. Thank you, Don p.s. I am not subscribed to this list, so cc'ing me would be appreciated.
