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". The

Hello I wonder whether someone can tell me what I am doing wrong. Here is the code (from Bayesian Computation with R - Chapter 2.3.R) that I am trying to run #################################### # Section 2.3 Using a Discrete Prior #################################### graphics.off() # Close all graphics rm(list=ls()) # Clear all variables library(LearnBayes)

Hello fellow R users, I have a problem. I have created a barchart overlayed by an xyplot line, both of which read off the same Y axis. The problem comes when I try to generate a key. It seems that I can only create either two lines, or two rectangles. I would much prefer to have the barchat series depicted by a rectangle, and the xyplot series by a line. Is there a way to do this? Your help

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 Ronaldo -- Aluno de

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

Hello, I have the following problem. I have created a couple of scripts to create .png graphic files from data plots, using the xyplot (lattice) command. When I refere to the script with source(""), the script will be red but there is no output file. The scripts work well with the regular plot command and produce a nice PNG file. On the other hand if I entre the single commands

Hi, I'm sure these are basic problems so I apologise in advance for my ignorance. I have a dataset with X, Y, and a Factor with 4 levels. I am trying to figure out how to use lm() to find the r2 value, slope and intercept of an X~Y regression, for each level of the Factor. Is there a way to do this automatically without having to specify different subsets of the factor? my code so far:

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

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 lattice graphics, the

Hi, I was trying to make a graph using trellis, and my code is: ----------------------------------------------------------------- library(lattice) makeGraph <- function(){ trellis.device() tbg <- trellis.par.get("background") tbg$col <- "white" trellis.par.set("background",tbg) # Test Data mfr <- matrix(sample(1:100,50,replace=T),ncol=2)

I have the following code that when executed from the command line works properly and produces a proper PDF. When the script is executed, the PDF produced is considered corrupt. I am using R 2.7.2 on Mac OSX 10.5.4. Thank you in advance for the help! library(lattice) pdf(file="CLDiag2.pdf") xyplot( CL ~ HT + WT + AGE + CREA + SEX, data=data2, outer=TRUE,

Hello listers, Does anybody know how to add text to an xyplot without whipping out the existing curve? That's all. For instance, Lets say you generate a graph like this A <- data.frame(x = rnorm(100), y = rnorm(100)) xyplot(y ~ x, data = A) How would you add 'Hello world'? I tried 6.02E23 different partial solutions found on the web and failed. I just need one EXAMPLE that

Hi R people I am using a function to create a pdf device, then send a lot of plots to it in a loop then a last lattice xyplot (itself within a function) outside the loop and finally call dev.off() to write to the file. This works well apart from the fact that the last plot does not get sent to the file unless I comment out dev.off() and then apply it in the console afterwards instead:

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

I have been using levelplot but have had trouble calling it inside functions - something seems to go wrong when it's not called directly from the R command prompt. Simplest reproducible example: $ R --vanilla > library(lattice) > levelplot(matrix(1:4,2,2)) - This gives a nice plot in soothing pastel colors. Now, with a file lptest.r containing 2 lines: library(lattice)

hello list! I'm sorry, I just stumbled over this strange behaviour (at least I am not able to explain the behaviour, therefore I assume it to be a strange behaviour): attach(water) # I know, this is not recommended names(water[3:10]) [1] "temp" "pH" "DO" "BOD" "COD" "no3" "no2" "po4" for (i in

Dear All, I have searched the following problem in the R help achives, and there did not seem to be solutio for it. The problem is how to break the axis in the xyplot (lattice plot). I read the posts using the package plotrix, buy it doesn't work with the xyplot, which is lattice based. A simple example is attached below: xyplot(c(1:10,100)~c(1:10,100)) What I would like to do is

For a non-log-scaled y-axis, I was able to change the appearance of the y tick labels in an xyplot by using a custom function for yscale.components. However I couldn't get that approach to work for when scales=list(y=list(log=TRUE)). What I'm trying to do is make the y-tick labels show up as something like (10, 100, 1000, etc.) rather than the default (10^1.0, 10^2.0, 10^3.0, etc.).

Hello, I would like to plot the following xyplot : for each date of fff (1 date per panel), bbb=f(aaa) for the two groups (ddd=1 and ddd=2) superimposed. I can do it by group (see below) but not together. I looked at http://lmdvr.r-forge.r-project.org/figures/figures.html but I haven't found what I was looking for (to be honest, I haven't understood all the examples). Any help will be

Happy New Year to all R users! I have two short questions concerning a xyplot with a color key: 1) How do I properly place (align) the color key beside the xyplot? As you can see from the code listed below, the placement of the color key is not correct. I would like the upper and lower end point of the color key to be perfectly aligned with the upper and lower line of the xyplot. Adjusting
