R help - May 2008 - Lattice box percentile plot

Dear Nabble.

I am trying to draw a box percentile plot with trellis using the panel in
Hmisc. I really want to colour the plots in. I can alter several of features
of the plot by changing the trellis par settings but I just can’t fill the
shape in.

Here is some example code which alters line colour and dot symbol:

require(lattice)
require(Hmisc)
A<-c(rnorm(100,50,2),rnorm(100,60,5),rnorm(100,55,7))
B<-rep(c(1,2,3),each=100)

trellis.par.set(list(box.rectangle=list(col="black")))
trellis.par.set(list(box.umbrella=list(col="black")))
trellis.par.set(list(box.dot=list(pch=3,col="red")))

bwplot(B~A,panel=panel.bpplot, probs=seq(.01,.49,by=.01))

I’d really appreciate it if someone could tell me how to change the fill
colour as well as it is driving me mad.

Chears.

it's a good question.. my guess is using "panel.bpplot" prevents
filling in
the shape "the coffins"- since the box is now two mirrored graphs. i
hope
i'm wrong.

trellis.par.get() 
br = trellis.par.get("box.rectangle") 
br$col = "black" 
br$fill = "lightblue"  #this is the parameter that fills in the box,
but it
doesn't work with panel.bpplot
trellis.par.set("box.rectangle", br) 
bwplot(B~A,probs=seq(.01,.49,by=.01)) 

thanks
y
