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.<BR>
<BR>
Has anybody faced a similar glitch before? <BR>
<BR>
Many thanks,<BR>
