I have an example where i plot an image and load it dynamically in an image analysis tool to create a film (dynamic graph). This works well under Windows but i can't plot to *.png or *.jpeg files under Linux (Ubuntu) with the same command. I'm using: png(file,width=200,height=200) or jpeg(file,width=200,height=200) Any help is appreciated With kind regards Marcel -- View this

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.

Hi all, Although R seems to have jpeg() and png() functions that converts data into jpeg and png formated files, it doesn't have functions the other way around. Does one of R contributed packages have gif, jpeg and png image readers?

Hello, When launching R from a script, when queried it reports the following capabilities as false: jpeg, png, x11 and cledit. When R is run from a terminal session, all of these capabilities are reported true. R is running on FC4. As the purpose of this script is to output the png file to a browser, it is unable to complete because of this. Any ideas are appreciated. We have an identical

Hi Community, here is the problem, Linux problem (reported to work on Windows). I need to generate graphical output in any of bitmap format under the 'R CMD BATCH'. Whereas the script generating png-s works perfectly in the R session, such things as X11, png and jpeg are not usable in BATCH (they cannot be switched on by --gui-X11 etc) and X11 is prompted to be required for png.

Hi everyone, I've been opening up R 2.0.1 from the dock and then starting the Mac OSX X11 server. After that I call >jpeg("test.jpg",plot(rnorm(10))) and r pops up a quartz window with the appropriate graph in it and puts a file called test.jpg into the HOME which is 0kb in size and is completely empty. There is no error message. I've tried >png("test.png",

Hello All, I am using library "party" and I have found a curious/strange behaviour when trying to save the output of a ctree in a file via jpeg/png command.

I have tried to install R-2.4.x on my computer (linux - mandriva 2007 - 64bits), with tar file for R-4.2.1 and rpm file for R-2.4.0, and function capabilities() says to me that JPG, PNG and TCLTK are not available.

Dear R-help I want to display an image file in a new plot frame. SVG is my preferred format, but I can also consider PNG, GIF, JPEG, TIFF, and PPM (from ImageMagick). By way of background (although not material to this posting), the image file is generated by a call to 'dot' (part of the 'Graphviz' suite) after the required .dot file has been produced using hand-crafted R code.

If I change the background color of a plot, with par(bg="red") for example, I get a plot with a red background when I use the postscript or X11 devices. With the png or jpeg devices, the background is white. Is this the intended behavior, or a bug? Is there anyway to get a non-white background with the png device? I'm using R-1.1.0 on Linux.

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,
