How to change parameters of Trellis-like graphs

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.

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?
