The following code runs fine on Linux, but not on my Mac. The error
message is given below, after the levelplot() call. I was able to run
lattice functions previously on the Mac without any problems. I don't
know what has changed. I searched R-help and found a similar problem
that wasn't answered. My Mac is running Xcode 2.5, in case that is
relevant.
