How to change parameters of Trellis-like graphs

Dear R-lists

I have just upgraded the version 1.5.1 from 1.4.1 in my laptop PC,
because, I have to prepare graphs by using the grid and lattice packages.
I tried it with 1.4.1, but I could not it.
After upgrade to 1.5.1, I have finished it.

Next, I tried to modify some graphs with as follows:
#
#  setting color for graph
#
library(grid)
library(lattice)
background <- trellis.par.get()
background$col <- "white"
show.settings()
background <- trellis.par.set("background",background)
show.settings()
names(trellis.par.get())
dot.symbol <- trellis.par.get()
dot.symbol$col <- "yellow"
dot.symbol <- trellis.par.set("dot.symbol",dot.symbol)
show.settings()
#
#
#
First, I could change the background color from Gray to White.
But, when the last code 'show.settings()' runs, R 1.5.1 have crushed on my laptop.
I have no idea such how to change the dot color of graphs.
Does anyone tell me how to change the graph parameters?

It crashes on Linux too.  You are not doing this right

background <- trellis.par.get("background")
background$col <- "white"
show.settings()
background <- trellis.par.set("background",background)
show.settings()
dot.symbol <- trellis.par.get("dot.symbol")
dot.symbol$col <- "yellow"
dot.symbol <- trellis.par.set("dot.symbol",dot.symbol)
show.settings()

works.
