Hi all - I'm trying to generate lattice barchart graphs with missing values, and came across the following: This does not run. I would expect it to: library(lattice) D = data.frame(X=1, Y=factor(letters[2], letters[1:2])) barchart(~ X, D, groups=Y) Error in grid.Call.graphics("L_rect", x$x, x$y, x$width, x$height, resolveHJust(x$just, : invalid line type which is simply

I would like to place the value for each bar in barchart (lattice) at the top of each bar. Something like the following code produces. library(lattice) mypanelfunc <- function(x, y, ...) { panel.barchart(x, y, ...) panel.text(x, y, labels=as.character(round(x,2)), ...) } myprepanelfunc <- function(x, y, ...) list(xlim=c(0, max(x)+.1)) mydata <- expand.grid(a=factor(1:5),
