Is this what you mean: Square plots, 1 row, 2 cols, 8 by 16cm cmToInch <- 0.393700787 pdf("test.pdf", paper = "special", height = 8*cmToInch, width = 16 * cmToInch, pointsize = 10, onefile = FALSE) opar <- par(mfrow = c(1,2), pty = "s") plot(rnorm(100), rnorm(100)) plot(rnorm(100), rnorm(100)) par(opar) dev.off() or same aspect ratio: pdf("test.pdf", paper = "special", height = 8*cmToInch, width = 16 * cmToInch, pointsize = 10, onefile = FALSE) opar <- par(mfrow = c(1,2)) plot(rnorm(100), rnorm(100), asp = 1) plot(rnorm(100), rnorm(100), asp = 1) par(opar) dev.off() or both: pdf("test.pdf", paper = "special", height = 8*cmToInch, width = 16 * cmToInch, pointsize = 10, onefile = FALSE) opar <- par(mfrow = c(1,2), pty = "s") plot(rnorm(100), rnorm(100), asp = 1) plot(rnorm(100), rnorm(100), asp = 1) par(opar) dev.off() HTH, G -- %~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~% * Note new Address, Telephone & Fax numbers from 6th April 2006 * %~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~% Gavin Simpson ECRC & ENSIS [t] +44 (0)20 7679 0522 UCL Department of Geography [f] +44 (0)20 7679 0565 Pearson Building [e] gavin.simpsonATNOSPAMucl.ac.uk Gower Street [w] http://www.ucl.ac.uk/~ucfagls/cv/ London, UK.
