Hello all, I am using quartz (on OS X obviously) to produce PDFs and PNGs from my plots, for later inclusion in LaTeX.
I am typically using something like: plot(0) dev.print(quartz, file="foo.pdf", width=5, height=3) dev.print(quartz, file="foo.png", width=5, height=3, dpi=72) I want the sizes of the PDF and PNG to be *equal* in *inches*, which works with dpi=72. However, when I increase the dpi parameter, instead of producing an image of the same size with increased resolution, it creates a larger image of resolution = 72. E.g. try dev.print(quartz, file="foo-72.png", width=5, height=3, dpi=72) dev.print(quartz, file="foo-300.png", width=5, height=3, dpi=300) system("open -a Preview.app foo-*.png") The inspector in Preview should show 72 dpi for both files. This is with: > sessionInfo() R version 2.10.1 (2009-12-14) x86_64-apple-darwin9.8.0 Is this a know bug/limitation? Is a solution planned? Is there a workaround for now? As a final note, I am aware that PDF is superior to PNG, particularly in a LaTeX workflow; but for particularly complex plots, I sometimes fall back on high resolution PNGs. Currently it forces me to add a 'scale' argument to includegraphics in latex for those. I would rather leave the latex document alone, use extension-less file names includegraphics and decide from R wether to produce a pdf or a png.
