Bug with the col option in plot function
3 messages · heyi xiao, David Winsemius
Really belongs o R-SIG-Mac list and have copied it there. I cannot reproduce on my Mac. I get the same colors on the pdf file with that code as I do on the screen device. I have in in the past needed to set up a device before plotting: trellis.device(device="postscript", color = TRUE) ... but you are not using a trellis function or creating postscript. What does utils::str(pdf.options()) return? On mine I get this List of 15 $ width : num 7 $ height : num 7 $ onefile : logi TRUE $ family : chr "Helvetica" $ title : chr "R Graphics Output" $ fonts : NULL $ version : chr "1.4" $ paper : chr "special" $ encoding : chr "default" $ bg : chr "transparent" $ fg : chr "black" $ pointsize : num 12 $ pagecentre : logi TRUE $ colormodel : chr "rgb" $ useDingbats: logi TRUE Perhaps this could be a cure?: pdf.options(colormodel = "rgb") You probably ought to update as well before raising the bug-flag.
