Doesn't that give you a warning? If not, you are using an older version of R (earlier than 2.0.0). In the latest version, ?trellis.device has a long rant on this issue. > but the body of the graphic > contains color. What is the code to create the whole thing in black > and white.

The easiest way to handle this would to replace 'pch=1:2' by 'par.settings = list(superpose.symbol = list(pch = 1:2))' (which may not work if your version of R is too old).
