[S] Adjusting Trellis plot.symbol

Dear Splus/Trellis Users,

I'm using stripplot(). Although I'm using Windows Splus 3.3, I have
access to 4.0 (a friends version) if necessary. I'm trying to,

1) Change the size of the plotting symbols.

I've tried the following with no success (in V3.3):

> tmp_trellis.par.get("plot.symbol")
> tmp$.cex <- 2
> trellis.par.set("plot.symbol",tmp)
> stripplot( ... )

The resulting plot does not show the expected change in the plot symbol

2) I'm also trying to add dotted lines similar to those plotted in
dotplot() default.

I have no clue on this one.

Any suggestions to make this work in V3.3 would be great, however, if
you only have suggestions on how to do the same in V4.0, I would
appreciate them as well. 

On a more general note, is there a reference that would be useful in better understanding how to work with Trellis plots ? My current reference is the V3.3 Trellis Users Manual.

Thanks, Kevin
