My question is so basic that I am (almost too) embarrassed to admit that 
I could not find an answer after an hour's worth of homework.

What is the Trellis / Lattice analog for the axis(graphics) function 
that enables the creation of axes in locations other than the default 
(i.e., bottom for X axis and right for Y axis) ?

For example when plotting mileage against weight (in American units), 
one might want to also include a second X axis on the top margin (e.g., 
axis() pos = 3) with fuel mileage in metric units.

xyplot(Mileage ˜ Weight, data = fuel.frame)

Thank you,

humbly yours,

Derek Eder
