The above mentioned procedure in customizing strip.factor is correct.
BUT one has to make sure that the trellis.device() get called
AFTER the change, so to summarize this proper procedure :
> trellis.settings.color<-trellis.settings.color
> trellis.settings.color$strip.factor<-trellis.settings.bwps$strip.factor
> trellis.device(openlook)
> xyplot( .... )
In the next release of Trellis, there will be a much easier way to change
setting parameters: through the use of a new function, trellis.par.set().
The new procedure will be :
> trellis.par.set("strip.factor", trellis.settings.bwps$strip.factor)
> trellis.device(openlook)
> xyplot( .... )
No local copy of trellis.settings.color is required.
