Two different yaxes with lattice plots

In "normal" plots, I can do an axis at side = 2 and a different one at
side = 4.  I've not been able to figure out how to do the same thing
with lattice plots.  The scales list can have only one sublist named
y.  I had thought of using a separate viewport alongside with the text
for the axis label, but I can't see how I could get the ticks to work.

You probably won't be able to do this in lattice (and I can't think of a 
sensible way to modify lattice to allow this that would work for multipanel 
plots). Why do you need lattice for this ? If this is a single-panel plot, 
you could use grid directly. Set the viewport to whatever you want, draw in 
it (you could use a lattice panel function to do that if you want), and add 
the axes with grid.xaxis and grid.yaxis.

Hello, I am using the sm and chron libraries to
produce density plots, they are lat/lon locations of
marine mammals.

I am using Windows 2000, 1.6.0

The default image plot for sm.density is yellow on a
red background - how can I change these colours? 
Neither sm.options nor par seem to cover this.

It seems that I can use sm.regression to weight the
density plots by attribute values at each point, but
this can only be displayed in "persp".  
Can I display sm.regression surfaces as "image"?  Or,
weight an sm.density surface by attribute value?

All I can think of is to increase the number of points
in an area in proportion to the value I would like
displayed.  (The value I am interested in is the time
between each point).

Cheers, Mike.
