[R] Sweave, lty = 3 line incorect in pdf output

[Ken Knoblauch]

Some follow-up after Achim's message,

If I open the Sweave created pdf, lty3Test-001.pdf, attached
to the first mail, with the display command from imageMagick,
indeed, the dotted line is present, but faintly, as with the
hardcopy printout, i.e., not respecting the lwd = 3 argument.
But, the dotted line is absent if viewed with Mac's Preview.app
and the pdf viewer of TeXShop.  I don't have acrobat on my
Mac to test that, but it seems to in part, at least, viewer related.
Still, it would be good to track this down and ideally solve
it.

Thanks.

Ken
