R help - Jan 2011 - lattice: par.settings with standard.theme() + additional arguments?

Dear expeRts,

I usually use par.settings = standard.theme(color = FALSE) to create lattice
graphics
without colors, so something like

library(lattice)
x <- runif(10)
xyplot(x ~ 1:10, type = "l", par.settings = standard.theme(color =
FALSE))

Now I would like to use an additional component in par.settings. I tried several
things
like

xyplot(x ~ 1:10, type = "l", par.settings = c(standard.theme(color =
FALSE), list(par.xlab.text = list(cex = 5, col = "blue"))))

but it doesn't work. I know I could use lattice.options() but is there a way
to get it
right ("locally") with par.settings?

Cheers,

Marius

Add it as a list element:

xyplot(x ~ 1:10, type = "l", par.settings = list(standard.theme(color
= FALSE), par.xlab.text = list(cex = 5, col = "blue")))
