Hi Concha

You nearly got there try:

set.seed(42)
D1 <- rnorm(200)
D2 <- factor(sample(letters[1:2],200,TRUE))
D3 <- factor(sample(letters[3:5],200,TRUE))
DF <- data.frame(x=D1,a=D2,b=D3)
print(bwplot(b~x|a,data=DF,
             par.settings = list(box.dot = list(rep("black",3)),
superpose.line = list(col = c("darkorange1","limegreen","magenta")), box.umbrella = list(col = c("darkorange1","limegreen","magenta")), box.rectangle = list(fill=c("darkorange1","limegreen","magenta"), col = c("darkorange1","limegreen","magenta"))),
             panel=function(x,...,col) {
             panel.bwplot(x,...,col=col[packet.number()])
                                       }
            )
     )

Dear all,

I would like to have the same color for the all boxplots from the same panel, but my code below shows the two colors alternating. Thanks!

set.seed(42)
D1 <- rnorm(200)
D2 <- factor(sample(letters[1:2],200,TRUE))
D3 <- factor(sample(letters[3:5],200,TRUE))
DF <- data.frame(x=D1,a=D2,b=D3)
print(bwplot(b~x|a,data=DF,col=c("black","black"),
par.settings = list(box.rectangle = list(fill=c("darkorange1","limegreen"))),
             panel=function(x,...,col) {
             panel.bwplot(x,...,col=col[packet.number()])
                                       }
            )
     )

Thanks,
Concha
