Hi
Here's a panel function that does what I think you want (NOTE that you
need to load 'grid' for this to work) ...
library(grid)
panel.tpop <- function(x,y,...){
panel.grid(h=length(agegrs),v=5,col="lightgrey",lty=1)
ls1 <<- list(...)
y <<- y
iFrame <- iEduDat[ls1$subscripts,]
iSex <- with(iFrame,unique(sex))
if (iSex=="Female"){
panel.pyramid(x,y,...)
iCc <- with(iFrame,unique(cc))
iYr <- with(iFrame,unique(yr))
totpop <- round(sum(abs(subset(iEduDat,cc==iCc &
yr==iYr,
select=value)))/
1000,2)
LAB <- paste("Pop = ",totpop," Mio",sep="")
xr <- max(abs(subset(iEduDat,cc==iCc,
select=value)))
xr <- xr - xr * 0.005
# Make the text label
tg <- textGrob(LAB, x=unit(xr, "native") - unit(1, "mm"),
just="right",
y=unit(max(y) - 2, "native"),
gp=gpar(cex=0.7))
# Draw box big enough to fit the text
grid.rect(x=unit(xr, "native"), just="right",
y=unit(max(y) - 2, "native"),
width=grobWidth(tg) + unit(2, "mm"),
height=unit(1, "lines"),
gp=gpar(fill="white"))
# Draw the text
grid.draw(tg)
} else {panel.pyramid(x,y,...)}
}

Dear R-users,
I am trying to add some text in a textbox to all panels in the following
example file. Using the panel-function, I can add a white rectangle with
panel.rect but then I have to fit in the text into the box by hand and it
will not automatically be centered. Does anyone know how to add the text
centered with a white box around it automatically? Is there something like
panel.textbox for lattice?
Thanks in advance and here is the example
