Okay, I see that default.units is set to "npc" and hence the behavior I mentioned. Looking at ?unit, I see the description of various units but it isn't clear which one I need to select to achieve the result I specified earlier. Maybe I'm missing something very basic, but I assume there must be a simple way to add text to an xyplot() at a specified (x,y) coordinate in the units of the plotted points?
