As described by the dev.copy() manual page, dev.copy(), dev.print(), and dev.copy2eps() all require that the device have the recording of graphics operations enabled to function properly. Most interactive (screen) devices have recording turned on by default, while most non-interactive (file) devices have recording turned off by default. Recording can be turned on using the command dev.control(displaylist = "enable") and off using dev.control(displaylist = "inhibit") which should only be done when a device is initially created. -Greg [Original author of dev.copy()] -----Original Message----- From: bioconductor-bounces@stat.math.ethz.ch [mailto:bioconductor-bounces at stat.math.ethz.ch] On Behalf Of James W.

If you want a jpeg, why don't you use the jpeg() function? jpeg("graph.jpeg", width=1000) plot(1:10) dev.off() Works identically for me interactively and via Rscript.
