Apologies if similar questions have appeared, I am new
to the net.

I am using xyplot to create conditioning plots and am
calling panel.superpose twice to plot two different factor
groupings.  I see how the superpose.symbol list can be copied 
with the trellis.par.get to see what the current settings are 
but I DON'T understand how to change the current settings so that
they are used in my panel displays.  

I want to use different pch symbols (change the superpose.symbol$pch
list) for each factor group in the first call to panel.superpose.  
I then want to use a single line type to join points belonging to a 
second factor grouping in the second call to panel.superpose.  This
second factor has a large number of factor groupings therefore I 
also need to change the length of the superpose.line list (if I 
interpret the error message correctly).

Any helpful suggestions appreciated.
