First, I want to thank everybody who responded for their
helpful comments and suggestions, though the problem is
still unresolved and if anyone has any additional ideas,
I would be grateful. Second, if I can test your patience
just a bit more, I have found an additional clue that
perhaps will help solve the mystery of the missing dotted
lines (on my system, apparently).
Recall the minimal example,
pdf(file = "test.pdf")
x <- 1:10
plot(x, type = "l", lty = 3, lwd = 3)
lines(x, 0.5 * x)
dev.off()
And the issue is that I don't see the dotted line in my viewer.
I do, however, if the file is created by
quartz(file = "testQ.pdf", type = "pdf")
x <- 1:10
plot(x, type = "l", lty = 3, lwd = 3)
lines(x, 0.5 * x)
dev.off()
but then the file generated is 72 Kb instead of 4Kb as with the pdf
device.
I tried on another Leopard system (64 bit R) with the same result, and then
on a system running Tiger (all with a version of R 2.10.1 patched),
The dotted lines appeared on Tiger. I transferred the Tiger generated
file to my Leopard Mac and the dotted line appears on the viewer,
here, as well. So, I investigated how the files might differ
and the only thing that I can find is that the Tiger generated
version contains the lines
1 J
1 j
whereas, in the Leopard generated version, I only see
1 j
If I add a line of 1 J to the Leopard generated file, after line 35,
the dotted lines do appear in my viewer.
I don't know what these commands do in pdf (I don't speak pdf).
Would anyone have an idea what could have happened that my pdf()
command does not produce them and most importantly, any ideas on
how to fix it?
Thank you, again, for your responses.

Thanks. By intended result, do you mean that the dotted line
in the viewed pdf file from the short code appeared correctly?
which would support the hypothesis that it is something specific
to my computer/setup or that it appeared as I had intended
the example to demonstrate? in which case, it is consistent
with a problem with Leopard.
It also worked correctly for me on Leopard (10.5.8).

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()
That one produces the intended result when run from the console, while
the attached file in your prior posting had the features you observed
(invisdble in Preview faintlt visible on Acrobat) on my mac 10.5.8
installation. R 2.10.1. Acrobat 8.1.7 and Preview Version 4.2 (469.5).
Hopefully, this is not yet another instance of R-Mac-FAQ 12.10
but something more easily treated.

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()).
