R help - Jan 2005 - Black and white graphics and transparent strip panels with lattice under Sweave

What is the most elegant way to specify that strip panels are to have 
transparent backgrounds and graphs are to be in black and white when 
lattice is being used with Sweave?  I would prefer a global option that 
stays in effect for multiple plots.

If this is best done with a theme, does anyone have a lattice theme like 
col.whitebg but that is for black and white?

I'm using the following with lattice 0.10-16, grid 2.0.0:

platform i586-mandrake-linux-gnu
arch     i586
os       linux-gnu
system   i586, linux-gnu
status
major    2
minor    0.0
year     2004
month    10
day      04
language R

Thanks,

Frank

I'd do something like this as part of the initialization:

<<...>>
library(lattice)
ltheme <- canonical.theme(color = FALSE)     ## in-built B&W theme
ltheme$strip.background$col <- "transparent" ## change strip bg
lattice.options(default.theme = ltheme)      ## set as default
