I received lots of replies to my original trellis question. In brief,
I wanted to know why xyplot wouldn't work inside a function of mine.
The answer is that trellis graphics returns a trellis object, but does not
necessarily print it. From the command line, printing is automatic, but
from within a function it's not.

Replacing "xyplot(...)" with "print(xyplot(...))" does the trick.

Dunlap, and A. Sinclair.
