Hello,

I would like to change the background color in only -one- of the strips in a
multipanel lattice xyplot, from the default yellow-brown color.
Until now, I only managed to change the background strip color in all of the
strips using the par.settings, but I do not get it to work for only 1 strip.

Below is the current code I am using.
The resulting plot is here:
http://dl.dropbox.com/u/9788680/01_DoseIntensity_MonitoringInterval_BW.pdf
(i.e. I'd like to color the "3 months" strip in red)

xyplot(value~ant|paste(intv, "Months"), groups=perc, data=di,
       type="b", layout=c(4,1),xlab="Prior anthracyclines",
lty=c(1,2),lwd=2,col="black",main="Dose intensity ~ Monitorings Interval",
       ylab="Dose intensity",
scales=list(x=list(at=c(0,0.5,1)),y=list(at=seq(0,1,.1))),
       par.settings = list(superpose.line=list(lwd=2,lty=1:2, col="black")),

       auto.key = list(space = "right", points = FALSE, ncol=3,nrow=1, lines
= TRUE, title="Percentiles", cex=.7, cex.title=.7, siz=6))

I would greatly appreciate it if someone could guide me in the right
direction!

Thanks

Coen
