lattice: drawing strips for single-panel plots
The strip argument to panel.xyplot seems to be ignored for single-panel
plots. Here is an example:
data(Chem97, package = "mlmRev")
myStrip <- function(...) { ltext(.5, .5, 'strip text') }
densityplot(~ gcsescore, data = Chem97, strip=myStrip)
The figure is printed with no strip. The strip.default documentation
suggests that Deepayan intended this behavior.

legend idea for latticeExtra
Dear list,
I've written a small utility function to add arbitrary legend(s) to a
lattice graph (or a combination of them), much like the legend
function of base graphics. I though perhaps it could be useful to
someone else, or improved by suggestions. I understand this goes
against the lattice paradigm somewhat, in that you short-cut the link
between group variables and the

Vertical line in densityplot?
Hi all,
I'm trying to get a vertical line at a specific point in a
densityplot. abline seems to be what's required, but it doesn't align
itself to the scale used in the plot.
example:
library(lattice)
x<-rnorm(100)
plot.new()
densityplot(x)
abline(v=0)
-----
The line seems to use some other coordinate system. What kind of call
do I use to make abline use the graph's

Adding a vertical line to plot with two overlapping density plots
Hi,
A simple question I hope. I wish to add a single vertical line to a plot
with several density plots.
Here is a simplified example.

thedata <- data.frame(x1=rnorm(100,1,1),x2=rnorm(100,3,1)) #create data
thedata.m<-melt(thedata)
densityplot(~value, thedata.m, groups=variable,auto.key=list(columns=2))

Multiple lattice plots on a page: aligning x-axes vertically
Dear R-help,
I am creating a two lattice plots (a densityplot() and xyplot()) that
have the same x-axes and then 'printing' them onto the same page, one
above the other (see end of email for an example to generate the graph).
With different labels on the y-axis for each plot the left spacing is
different, and the x-axes don't align vertically. Although I can
manually modify the

Separate ablines in lattice panels
Searched archives and found some old email threads on the topic. But mot exactly what I think I need. Suppose I have a datafile such as tmp.
tmp <- data.frame(var1 = c(rnorm(1000), rnorm(1000, 1, 1)), var2 = gl(2, 1000))
I'd like a plot similar to the one below, but with an abline of v=0 in the lower panel and v=1 in the upper panel. Code below creates two lines in each panel, not quite

call lattice function in a function passing "groups" argument
I'm trying to use a lattice function within a function and have problems
passing the "groups" argument properly. Let's say I have a data frame

and want to plot variable x in a densityplot, grouped by the variable y, then
I would do something like

Problems drawing a colored 'rug' in the Lattice 'densityplot'
Hi All,
I'm trying to add a 'rug' representation of my data to a plot created

How to generate a figure using par( ) with some densityplot( )'s
Hi Dear R users,
For a pair plotting, usaully we use par( ) function. Apparently it does not work anywhere. I want to have 3 plots in a single figure, like this:
par(mfrow=c(3,1))
densityplot( a)
densityplot(b)
densityplot(c)
But it does not work. How is it possible to have such a figure with densityplot( ) in a single figure?
So many thanks for any help.

small issue with densityplot
Hi folks,
This is really minor but to someone not familiar with the various tentacles of the lmer package it could be really annoying. I was trying to plot the posterior density of the fixed effect parameters of a lmer model,

> densityplot(hr.mcmc, plot.points=F)
There is this error,

Lattice densityplot with semitransparent filled regions

I'm doing some graphics for a paper and a need customize such with filled

How to adjust y-axis when using panel.densityplot within histogram function
Hi
I would like to superimpose group-specific densityplots on top of an overall
histogram using panel.histogram and panel.densityplot. Furthermore, I would
like to automatically adjust the range of the y-axis to take into account
the ranges of both histogram and densityplot. This last part is where I have
a problem. I believe using the prepanel argument of histogram is typically
the way to go,

density plot text
Is there any way of adding text to a density plot? I have had a go using the
text() function but I think the error is because this function doesn't work
with densityplot().
Alternatively, I understand I can achieve pretty much the same result if I
plot a density kernel estimate using plot() (which allows text()), but I do
prefer densityplot().
Also, is it possible to specify the dimensions

does'nt work and in R i dont have any output
but if i launch by R row by row, runs correctly.....
