I've been unable to solve this problem using all sorts of variants of
trellis.par.set, or par.settings within xyplot.
I need this plot not to be transparent, so when I drop the .ps into
LaTeX it shows up on my black slides.
thanks.

traj.female<-read.delim("d:\TRAfemales.dat", header = TRUE, sep = "\t")
#This is the key to getting the right legend
trellis.par.set(superpose.line=list(lty=c(1,2,1,2,1,2),col=c(1,1,2,2,3,3)))
trellis.par.set(background=list("gray"))
# This works
female.traj<-xyplot(TRA~Grade, data=traj.female, groups=Group,
type="l", lwd=2,
lty=c(1,2,1,2,1,2),
col=c(1,1,2,2,3,3),
auto.key = list(
lines=TRUE,
points= FALSE,
x = .25, y = .7, corner = c(0, 0), border=TRUE),
xlab="Grade", ylab="TRA",
ylim=c(-.5,6.5),xlim=c(0.5,6.5),
panel=panel.superpose,
#par.settings=list(background="white",transparent=FALSE)
)
female.traj
