Note that pdf does not 'display' anything: it writes a file. From
?pdf
If you see problems with PDF output, do remember that the problem
is much more likely to be in your viewer than in R. Try another
viewer if possible. ...
So which viewers are you using?
I see no reason why pdf() should produce different output on your Mac
from anyone else's build of R, and indeed I just ran this on a Mac (R
2.10.1, Snow Leopard) and viewed it in Preview and Acroread 9.3.0 with
no issue. And I transferred the file to Linux and viewed it on several
PDF viewers there.
One possibility is that this is an issue in Preview only on 10.5.8
(aka darwin9.8.0), or it might depend on the screen resolution or just
about anything else specific to your machine.

Indeed, you are right. That is where the problem is.
Thanks for helping localize it a bit further.
So, I should cc this to the r-sig-mac list.
For the r-sig-mac list, here is the original post on the r-help
https://www.stat.math.ethz.ch/pipermail/r-help/2010-February/227832.html
The pdf() command (at least on my Mac :( ) appears to have
a problem in displaying dotted lines (lty = 3).
Short example,
pdf(file = "test.pdf", height = 6, width = 6)
x <- 1:10
plot(x, type = "l", lty = 3, lwd = 3)
lines(x, 0.5 * x, type = "l")
dev.off()
Hopefully, this is not yet another instance of R-Mac-FAQ 12.10
but something more easily treated.

Quoting Achim Zeileis <achim.zeil...@uibk.ac.at>:
Ken,
an idea off-list: Have you tried
pdf(file = "test.pdf", height = 6, width = 6)
...
dev.off()
with your code? This is essentially what Sweave should do internally.
If that replicates your problem, it might be a hint that something with
pdf() is not working on your machine (rather than Sweave()).
