Not generating line chart
Hi All, Can you please help me, why this code in not generating line chart? library(ggplot2) par(mfrow=c(1,3)) #qplot(TIME1, BASCHGA, data=Orange1, geom= c("point", "line"), colour= ACTTRT) unique(Orange1$REFID) -> refid for (i in refid) { Orange2 <- Orange1[i == Orange1$REFID, ] pdf('PGA.pdf') qplot(TIME1, BASCHGA, data=Orange2, geom= c("line"),

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". The

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

bwplot in loop doesn't produce any output

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 lattice graphics, the

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?

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?

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

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: ---- trellis.device(device="pdf", new=TRUE) trellis.par.set(my.theme()) dotplot(Y ~ X | C, groups=G, data=D, layout=c(2,1), ... ) trellis.focus("panel", 1, 1) for (y in 1:5) {

problem with a densityplot
Hi, i have a script how i launch lattice to make a densityplot. in the script: jpeg(file="XXX.jpg") densityplot(~f_diametro+m_diametro+n_diametro, plot.points="rug", auto.key=T) dev.off() does'nt work and in R i dont have any output but if i launch by R row by row, runs correctly..... any idea?

Problem with xyplot when creating a .png graphic
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

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

need some lattice help
Hello everybody, I just started with lattice plots and I was wondering why it behaves different than expected. If I generated multiple plots in the past, I just used some code like this: lapply(..., { windows() plot(...) }) I got multiple windows, each containing one plot. Now, I tried the same with "levelplot" (instead of "plot") and I see all windows are created but

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() >} >test() 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.) INFO: R version 2.9.1 (2009-06-26) using Windows/RGui require(lattice)

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

function to display histogram fails to do so when histogram is not the last expression in the function
TestHistogram_A is a function that plots a histogram, then returns 3. For me it fails to display the plot, at least in the order given below. TestHistogram_B is a function that plots a histogram, then exits. The only difference between the 2 functions is that B does not return 3. It displays the plot. This problem does not occur when histogram is replaced by boxplot Their use

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) }
