It is true that Preview.app took an inordinately long time to display on my system (MacOS 10.6.8, Preview 5.0.3, Mail 4.6), but going out to refill my coffee cup did let it succeed. I didn't try with QuickLook.

In the example below, R displays the plot correctly with 2 curves in solid lines, 2 curves in dashed lines and 1 curve as a dotted line. However, when I save the image as PDF (as attached), the dashed lines become solid. This also happens if I use the pdf command directly (by removing the # symbols).
