R help - Nov 2010 - lattice mutiple y scales in each panel

Hi,

I have a data set with two y variables (y1 and y2) and one dependent
variable(x) and a 1 strata variable Z. It so happens that y1 and y2 have
very different scales such that single y-axis scale doesnot allow the data
to be visualized fully.

I am trying the following lattce graphics to do my plot :

xyplot(y1 + y2~x|Z,data=D,type="b")

This provides the appropriate plots by due to big scale differences y1 and
y2 cannot be viewed together on a same scale
i want to know if there is a way in lattice graphics to add an additional
scaling to the right y-axis in addtion to what's there on the left so that
the plot makes more sense.

Thanks

gives the answer (search for latticeExtra) ... it also gives some 
reasons why you might not
want to do this.
