R help - Jan 2008 - on trellis.par.set/get (reproducing figures from Pinheiro & Bates)

Dear R users,
I would like to exactly reproduce a figure like the 1.5 or 1.9 or 4.13 
from the book
Mixed effects models in S and S-Plus.
Not for the sake of it, but because I have my own data I would like to 
plot in that fashion
(no colors)


If I write

plot(ergoStool)

I can get a good informative plot with colors, but I would like to have 
a B&W one instead.

I've played a little with trellis.par.set
managing to change some aspect of the appearance of the plot,
for example with

prove.theme<-
  list(
       dot.line = list(col = 1, lty = 3, lwd = 1),
       fontsize = list(text = 12, points = 10)
             )
trellis.par.set(prove.theme)
plot(ergoStool)

I also queried trellis.par.get by

names(trellis.par.get())

but still I'm not able to figure out which are the parameters, if any,
that control "pch" and "col" of the symbols.

Any help is highly appreciated.

Have you tried

trellis.device(color = FALSE)
plot(ergoStool)

Thanks once more for your help.
It works but the symbols are not the same as reported in the book.
Now, if I can push your patience a little further, how can I change the 
plot symbols ?

The symbols happen to be controlled by the "superpose.symbols"
setting; other than guessing from the names, this is also indicated by
the output of

show.settings()

So to change it, you would do

trellis.par.set(superpose.symbol = list(pch = <...>))

or some variant of this.
