lattice density plot: add vertical lines at groupwise medians for all panels
Suppose you have the following code:
########## Start code##########
data(Chem97, package="mlmRev")
densityplot(~gcsescore | factor(score), groups=gender, data=Chem97,
auto.key=TRUE, plot.points=FALSE, ref=TRUE,
panel=function(x,...){
panel.densityplot(x,...)
median.values <- median(x)

lattice: defining grouping variable only for the upper/lower panel with splom
Using the mtcars dataset, how to define the grouping variable to be valid
only for the upper or lower panel?
The following doesn't work:
# Code start
splom(~data.frame(mpg, disp, hp, drat, wt, qsec),
data=mtcars, pscales=0,
auto.key=list(columns=3),
upper.panel = function(...){
panel.grid(...)
panel.xyplot(groups=cyl,...)
}
)
# Code end

[lattice] print only legend
Is it possible to plot (and save) only the legend of a lattice plot? Of
course I could make the axes and axis labels transparent and use an empty
panel function, but additionally to being a very "dirty" solution, there
would be still a lot of free space on the plot, while I would like to save
only the legend as a separate plot without any white space around it. Is
there a (nice) way to
