Hi All The device commands pdf and postscript allow you to specify the width and height of a page. However, each subsequent plot is drawn on a separate page. Is there a way to change the page size part way through? For instance, is there an equivalent to the function pdfresize below? pdf("/tmp/1.pdf", width=6, height=6) plot(1:10) pdf.resize(width=8, height=5) plot(sin, -pi, pi) dev.off() --- So far, the only way I can find to do this is: pdf("/tmp/1.pdf", width=6, height=6) plot(1:10) dev.off() pdf("/tmp/1.pdf", width=8, height=5) plot(sin, -pi, pi) dev.off() --- however, this creates a new file - it does not append to the existing file. I would note that the quartz device has some resize capability, when you drag the window frame. -Alex
