[R] plot bg color in Mac OSX

    I am running R on my iBook (OS X 10.4) and whenever I try and plot a model that has been run, I get a grey background. This makes the plot difficult to read on b&w printouts. I have tried changing the background to white (or any other color) without any success. Here's a current example

plot(augPred(m2corn.nlme, level=0:1), bg="transparent", lty=c(1,4), pch=19, cex=.75,new=TRUE)
plot(augPred(m3corn.nlme, level=0:1), lty=c(1,4), pch=19, new=TRUE)

Notice that if I run this code at the same time, there are some par arguments that work as I would expect and others that seem to have no effect. For example, bg="transparent" and new=TRUE both seem to be ignored. This is annoying because teh grey background makes light colors difficult to see. Additionally, I would like new=TRUE to work so that I can actually create these two plots at the same time. Any ideas on how to get this to work?
