Hi R colleagues, I don't know whether this is a bug, but something weird happen with R-GNOME. Version 1.5.0. I compiled the stuff under i-686 Linux RH 7.2 using ./configure --with-gnome. R can be started with or without the Gnome interface: fine. However, when I start with Gnome interface, jpeg and a few other things are unavailable (checked using capabilities()), whereas everything is

Hi I have been creating very, very long jpeg images for the last two weeks using jpeg(). All of a sudden, and I mean that, it's stopped working - I've not changed a thing! The error message I get is: > jpeg("out.jpg",width=50000,height=480, quality=100) Error in devga(paste("jpeg:", quality, ":", filename, sep = ""), width, : unable

r-help?? When I want to use jpeg() in R-2.1.1 which is installed in linux platform to generate a jpeg file, the error occurs as following: > jpeg() Error in X11(paste("jpeg::", quality, ":", filename, sep = ""), width, : unable to start device JPEG In addition: Warning message: unable to open connection to X11 display '' > capabilities()

I love the new tiff(), jpeg(), and png() in R 2.7.0 but found an issue that I didn't see reported. When specifying 'units = "in"' but forgetting to change the default height and width (so the figure is unintentionally going to be 480 inches by 480 inches) I run into problems. Here's the reproducible example: tiff("a.tiff", units = "in", res = 1200,

Dear R gurus, Trying to loop a graphing function and output a jpeg file each loop. It works fine for a single run (ie. not looping) but when I loop the output is nothing but white space. Here is my code, somewhat abridged: { <rest of loop> jpeg(filename=<"name for this loop.jpeg">) xyplot(AbvBioAnnProd~Year|factor(Plot), type = c("b", "r"), pch =

Hi all, Is there a way to compare time series using cave plots with R ?

Full_Name: Steve Koehler Version: 1.8.1 OS: Solaris and Windows Submission from: (NULL) (192.55.214.50) In the following program, if output is sent to X11, you get all four graphs, but if output is sent to .jpeg, you only get the C and D graphs. A workaround is to do all the screen splitting at the top, before using any screens. This also fails with .png output. jpeg ("test.jpeg")

New years greetings. I have been setting up a function to generate multiple jpeg charts. When the calls are issued at the interactive console, the jpeg files are generated without an issue. When I try to issue the same calls from a function, some chart files are empty. It appears to only be related to trellis charts. Any help to troubleshoot this is appreciated.

Hi everybody, I just notice a strange behaviour of gpar's fill argument when using non-postscript devices: The default of the argument is transparent (according to get.gpar("fill")). So as expected, the following code draws a nice red rectangle in the middle of my X11 or postscript device. pushViewport(viewport(width=0.5, height=0.5)) grid.rect(gp=gpar(fill="red"))

Hallo R-experts, I produced a R graphic with the help of the following commands: plot(0:4,0:4, type = "n", xlab = "X-Werte", ylab = "Y-Werte") points(rnorm(100), rnorm(100), col = "black") locator(2, type= "l") locator(2, type = "l", col = "red") I could display this graphic by using windows() before entering those commands.

Colleagues, Using R 2.10.1 in OS X (Snow Leopard), I created JPEG documents that were intended to include italicized text. In the JPEG versions, the italics appear in bold-face. The identical code (except for the call to the device) yields italics in PDF. A minimal example is: PDF version: > pdf("plot.pdf") > plot(1,1) > mtext(bquote(italic(P) < .(0.005))) >

Hello everybody, if I'm using par(xpd=NA) gridlines will plotted outside the plotting region. This is "new" (and, in my opinion, unaesthetic) in version 1.4 - compared to version 1.3. Is this a bug or a feature? Example: ------------------ par(xpd=NA) plot(1:11) grid() ------------------ platform sparc-sun-solaris2.6 arch sparc os solaris2.6

Dear colleagues, I just upgraded to 1.4.0 version from RH RPM on a RH72 linux i686 machine. Maybe I am the only one, but when I tried then to install 2 packages (namely pspline and xgobi), weird things happened. First on call of library(xgobi) or library(help=xgobi), all looks good, but on call of ?xgobi, or data(PaulKAI), or when trying to look at html help, the package seems empty. More

Hi there, Does anybody have experience in running jpeg device using xvfb-run on linux? I've been having sporadic problem with: /usr/X11/bin/xvfb-run /usr/bin/R --no-save < Rinput.txt, with error saying: error in X11 connection. Especially when I run it from a perl script. Is there a better way of doing this? or how can I fix the problem. Thanks in advance! David [[alternative HTML

Using R-1.1.1 on RedHatLinux 6.2. I've made some progress, succeeded in outputting bitmap, jpeg, and png files. Yipee. I did them with this command: > dev2bitmap("whatever.bmp",res=300) > dev.print(png, file="myplot.png", width=480, height=480) > dev.print(jpeg, file="myplot.jpg", width=480, height=480) > dev.print(pictex,

Hello, I am running some commands in batch on a server that I SSH into; some of the commands call jpeg(). If I continue to stay signed on (with my xwindows working on my machine) then the jpeg() command works (with a single caveat, below). If I leave it and sign off (with a nohup command in front of my BATCH) then jpeg gives me an error like this: Error in X11(paste("jpeg::",

Hello, I'm starting using R and runned a little script. The generated graphic could be exported correctly with RGui.exe ("file -> save as -> jpeg -> etc.") But if I try to run the same script with Rterm.exe and followed by: jpeg(file="test.jpeg", quality=90) The created jpeg file is completely white without any color, do you know why ? Sum up of the script:

Hi I cannot seem to create any files that have the name "CON" before the file extension, i.e. all of the following fail: > pdf("CON.pdf") Error in pdf("CON.pdf") : unable to start device pdf > jpeg('CON.jpeg') Error in jpeg("CON.jpeg") : unable to start device devWindows > png('CON.png') Error in png("CON.png") : unable

I installed jpeg package and tried to use kim<-readJPEG("kim.jpeg") to read in a jpeg file, but R gave me an error: Error in readJPEG("kim.jpeg") : unable to open kim.jpeg I already put "kim.jpeg" in Rstudio's default working directory: "E:\home work\Rstudio". So I don't think it's a problem caused by omitting the file's path. But I
