Hi,
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?
Most nlme plots are Trellis plots (using the lattice package), where traditional graphics rules don't apply. You need to read up on lattice. ?lattice would be a good start. -Deepayan
