[R] Adding margin text to lattice graphics

I am learning lattice graphics (R 2.12.2; OS X). Several days ago, I inquired about adding margin text to lattice graphics. Jim Price offered a useful reply, suggesting that I add:
page = function(page) grid.text('words', x = 0.5, y = 0.01)
to my call to the function. The entire function that he suggested was;
xyplot(1 ~ 1,
par.settings = list(layout.heights = list(bottom.padding = 10)),
page = function(page) grid.text('words', x = 0.5, y = 0.01))
That worked initially and I also had success with panel.text.
However, I am now working with more complicated objects in which more than one image is displayed on a page. In this instance, the text added by the command above appears with each image. I would like it to appear only once, scaled across the entire page, not relative to a single panel.
Is there a different command that accomplishes my goal? Or a different implementation of this same command? Any help would be greatly appreciated.
Also, because of my naivete with lattice graphics, I may be asking the question in entirely the wrong way -- please feel free to redirect me.
