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
