Graham, is your script portable > to Windows and Mac? Could you share it with us? Maybe we can propose > this feature to LyX developers. It will be definitely helpful. > Although I do normally use SWeave, these particular files were simply exported from R, and then imported into Lyx, there just big PDFs. ECDFs based on 120,000 data points, which is why I suspect they are large without some form of flattening. But compressing imported PDFs goes beyond R and maybe qpdf could become a Lyx feature to optimise PDFs the same way that MSWord allows you to optimise graphics before saving/printing. The Nautilus script in Linux uses Ghostscript and maybe this could be another option to consider along with qpdf. http://www.webupd8.org/2010/11/download-compress-pdf-12-nautilus.html But I will have a look at qpdf, thanks, Graham
