Sweave, lty = 3 line incorect in pdf output

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.

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.

Thank you.

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()).
