Problems with xyplot
Hello
I wonder whether someone can tell me what I am doing wrong. Here is the

One question about saving graph by using xyplot
Hey, folk.
I am trying to get many figures by using the function "xyplot" in the library "lattice". I tried to using the loop to finish it quickly. But I cannot open the saved file after I run the program. But if I use the function "plot" to get other simply figures, it can work. So I want to ask how I can get the saved figures by using "xyplot".

Problems with lattice-histograms or png within loops
Dear R-users,
I have a question concerning the use of lattice plots within for-loops.
I want to create a png file containing a lattice histogram which works out
fine (part 1).
When I loop the whole code, the graphic file does not contain anything (part
2).
I can fix it by wrapping the histogram function into a print command (part
3).
Why is that so? Why can I not loop it directly?
TIA,
Mark

xyplot source file only work with echo=TRUE
Hi,
I write several xyplot graphics on a source file. When I try to use
source("graphics.R") the source don't work, but if I use
source("graphics.R",echo=T) it work. Generally some commands work without
echo=T, but xyplot dont work. Why it dont work without echo=T? It is possible
to write a source that dont need echo=T on source command?
Thanks

XYplot in Lattice Package
Dear R-Users
I have 2 questions to do with XYplot.
1)
I am trying to use the XYplot function to generate multiple line graphs with
the legend outside the plot.
I am using the following loop for each graph:
library(lattice)
for (i in x.sp){
xyplot(Catch~Year, df, groups = Stock, type="a",auto.key =
list(space = "top", points = FALSE, lines = TRUE,columns = 4))

ActiveSupport not including i18n?
Went to use ActiveSupport in a gem today and got an error on account of not

Iterations
I have a command that reads in some data:
x <- read.csv("Sales2007.dat", header=TRUE)
Then I try to organize the data:
sc <- split(x, list(x$Category, x$SubCategory), drop=TRUE)
Then I want to iterate through the data. I was able to get the following to run on the R console:

sum(sc[[i]]$Quantity)

Lattice trellis.focus() with pdf
Hi,
I have a the code for a plot that works perfectly running in R and
printing to a Quartz object but which doesn't work when I make the
trellis device a pdf.
The code is as follows:

Call trellis function in a function (PR#8827)
Full_Name: Fan
Version: 2.2.1
OS: Windows
Submission from: (NULL) (159.50.101.9)
Hello,
When I call trellis function (such as histogram, densityplot, etc.) in a
function,
the call seems being ignored (no graphics is drawing) if some other instructions
are placed afeter that call.
Here's an example:
y = rnorm(100*3)
b = sample(1:3,300,replace=T)
f = function()
{
densityplot(~y|b)

lattice graphics empty in Sweave
Hello,
I have problems using lattice graphics together with Sweave under
Windows XP and R 2.0.0; 2.0.1 Patched; 2.1.0 devel respectively.
Base graphics are o.k., but for lattice graphics empty files (.eps and
.pdf) are generated.
The only workaround I found was to write and read the respective figures
explicitely using postscript() and includegraphics{}.
Have I missed something to solve this

Color eps/ps output from specialized plots?
Hello,
First a disclaimer :) I am very new to using R.
I am generating some plots and eventhough I can get colored output in the encapsulated postscript files in the simplest of commands (e.g. plot(1:10,1:10, type="l", col="red") ), it does not work for the particular plots I want. It works on the screen.
Here is an example taken out from "Mixed-Effects Models in S and

lattice graphics and source()
Hi,
I am trying the lattice graphics in R. Let's say, such a little
experiment in file myprog.r:
f <- function(){
x <- 1:10
y <- x^2
xyplot(y ~ x)
}
f()
Then I run the program:
> source("myprog.r")
but nothing happens. Manully run f() at the command line:
> f()
then the figure is shown. This seems to be a bug only associated with

bug: wireframe and tcltk
Dear R users,
When i call the wireframe function from within a tcltk widget, it does
not work.
Here is a sample program that shows the bug.
When you try:
is.it.a.bug()
You can see that the "curve" instruction is run but not the "wireframe" one.
Do you have an explanation about this point?
Best regards,

Problem with plotting data from within a function
Dear List,
I try to develop code where plotting functions are embeded in my own
functions. The following is simplified example:
> test <- function() {
> data <- data.frame(x=rep(1:2, each=50), y=rnorm(100))
> library(lattice)
> attach(data)
> xyplot(y~x)
> detach()

As far as I understand R, when test is called this should create one local

Lattice barplot not wokring in for-loop?
Dear List-Members,
I am plotting a barplot with the lattice package. The code works, but
when I execute the same code in a for-loop
no plot is shown. Can't figure what the problem is.
(Maybe I am missing something here, but I tried it with plot device
pdf, calling windows() or X11(), testing on windows and linux, etc.)

lattice: plotting in a loop
Hi,
I'm having trouble seeing graphics output from lattice xyplot() when called
from inside a for loop:
x <- 1:50
for ( i in 1:5 ) {
y <- rnorm(x)
xyplot(y~x) # no graphics when inside for-loop
# plot(x,y) # works fine
# Sys.sleep(0.5) # doesn't seem to help
}
The xyplot() is fine outside the loop. Results are the same to X11 device
and to file
