R help - Aug 2007 - setup trellis.device to color=F inside the xyplot function

Hi,

it is possible to setup trellis.device(color=F) inside teh function xyplot?

I try to use 
> xyplot(ocup~tempo|
nitro+estacao,col="white",ylim=c(0,0.7),par.settings=list(color=F))

But dont work, the only way that work for me is call the function
> trellis.device(color=F)
before the xyplot, but in this way it open a new device for each run. I like 
that is use the same device every time, but without colors.

Thanks
Ronaldo

Try this:

library(lattice)
x <- 1:10
y <- 1:10
g <- rep(1:2, 5)
# no color
xyplot(y ~ x | g, par.settings = standard.theme(color = FALSE))
xyplot(y ~ x, groups = g, par.settings = standard.theme(color = FALSE))
# with color
xyplot(y ~ x | g)
xyplot(y ~ x, groups = g)
