replicates in repeated ANOVA
Hi,
I have sort of a newbie question. I've seriously put a lot of effort into how to handle simple replicates in a repeated ANOVA design, but haven't had much luck.
I really liked reading "Notes on the use of R for psychology experiments and questionnaires", by Jonathan Baron and Yuelin Li ( http://www.psych.upenn.edu/~baron/rpsych/rpsych.html ) but still didn't run across

Different gridlines per panel in xyplot
In the example R script below, horizontal gray gridlines are drawn at y
coordinates where the points are drawn with the code:
panel.abline(h=y, v=xScale, col.line="gray")
How do I change this so that the horizontal gray gridlines are drawn at y
coordinates where the y labels are drawn? The challenge is that each panel
has different y-ranges (in my real example the y-ranges and

Hmisc and Lattice question on gridlines
I have been using lattice xyplot and am quite pleased, and I can use the
type=c("b","g") to have it print gridlines into the page, yet if I want to
have a line plot with points on it, how do I get the xYplot to print
gridlines (I use Hmisc xYplot because of its bands method which allows
plotting of confidence intervals). Any suggestions? I have looked at the
panel functions but

Question about barplot: gridlines & value labels
Hello!
I promise I looked into help files before asking. Still cannot figure
it out. I think it's because I am totally confused what packages use
lettice, which use trellis, etc.
Sections 1 and 2 below produce the data and the data to plot. My
question is about barplot in Section 3. I am trying to:
1. add only horizontal gridlines and manipulate the type and color of
that line. tck = 1 is not

Thank you for providing advice on this graphics question.
I am building an interaction.plot.

plotting gridlines
dear all,
I have a very simple question but I could not figure out.
I need to make plots with grid in the background.
something like I old retrive like this
a=runif(100)*10
b=runif(100)*10
plot(a,b, pch=20, xlim=c(0, round(max(a))), ylim=c(0, round(max(b))))
vs=seq(0, max(a), 0.5)

Suggestion for read.table()
First, I compliment you all
for such a useful project as R.
Suggestion: If read.table() could
take input from a character string,
then one could write
raw=
" x y z
1 2 3
4 5 6
"
df = read.table(raw,head=TRUE)
Of course, one can
cat() to write raw into a
temporary file,
and read.table() from that file.
However, direct reading
might be a good option?
Hope this is

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

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

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,
