Wow, you must like light colors :) To the point, just set margins, for example par(mar = c(2,2,0.5, 0.5)) (margins are bottom, left, top, right) after the Cairo command. BTW, Cairo doesn't work for me either... but I tried your example by plotting to the screen. Peter Notice how the canvas' margins are relatively far from the plotting area. > > Thanks, > > Eduardo > > On Thu, Jan 6, 2011 at 1:00 AM, David Winsemius <dwinsem...@comcast.net>wrote: > >> >> On Jan 5, 2011, at 9:38 PM, Eduardo de Oliveira Horta wrote: >> >> Hello, >>> >>> I want to save a pdf plot using Cairo, but the canvas of the saved file >>> seems too large when compared to the actual plotted area. >>> >>> Is there a way to control the relation between the canvas size and the >>> size >>> of actual plotting area? >>> >>> >> OS?, ... example? >> >> == >> >> David Winsemius, MD >> West Hartford, CT >> >> > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
