broken lines with quartz device
Me culpa - it's a bug in Quartz code that uses bitmap rendering (i.e. on-screen and bitmap formats) which splits lines to segments for faster rendering and produces a gap between such segments. It should be fixed in tonight's nightlies. Thanks, Simon

Dear all, I've just installed R on a new MacBook Pro, and I'm facing the following issue: continuous lines in some graphs appear with a discontinuity when I use the quartz or png() device. I really don't think it comes from this specific code as the pdf() output is fine, and so is the output on other machines. I have no clue where the problem is, I can't nail down what triggers it (I haven't been able yet to create a minimal example, sadly). The screenshot attached shows the result of the pdf() device vs the default quartz() device, note the broken lines in the middle of the right side graph. Has anybody faced a similar glitch before? Many thanks, baptiste sessionInfo() R version 2.7.1 (2008-06-23) i386-apple-darwin8.10.1 locale: en_GB.UTF-8/en_GB.UTF-8/C/C/en_GB.UTF-8/en_GB.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base <image.png> PS: apologies for any duplicate, i've been trying to send to this list for 2 days without any apparent success.
