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

[Achim Zeileis]

Ken,

I can't contribute much, just that I tried to look into it and can't 
replicate it. I tried it both with .Stex and .Rnw yielding identical 
results, just like plotting it interactively (on my default X11) and 
printing it via dev.copy2pdf(). All of the approaches seemed to yield the 
same output which looks ok.

Just for the record...
