I'm trying to get a plot with wide lines that don't have rounded end caps. You can see the effect quite clearly with a plot like this: plot(0:1) lines(c(1.5,1.5),c(0,.5),lwd=20,col="red") lines(c(1.5,1.5),c(.5,1),lwd=20,col="green") abline(h=0) abline(h=0.5) abline(h=1) The colored lines should be between the horizontal lines, but because of the rounded end caps,

I'd like to put a degree symbol in the title of a plot. Something like: plot(1,main=expression("Data at " * 45 * degree * " North")) That works fine, but I like the 45 to be the value of a variable, instead of a constant, an in: lat <- 45 plot(1,main=expression("Data at " * lat * degree * " North")) But this doesn't work of course, the graph

I have a non-PS printer setup to print under linux using ghostscript as a filter. This printer has two paper trays, one has letter paper, the other tabloid size paper. If I print from a program that uses a PPD file to configure the printer, like StarOffice or The Gimp, I can select the paper size from a nifty list. If I select letter size, the printer print with paper from the letter tray. If

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.

I am generating images via lattice from Frank Harrell's RMS package. These images are characterized by coloured lines and grey-scale confidence intervals. I need to port them to Openoffice/etc, and have tried both png and jpeg (at high quality), but in neither format can I subsequently see the the grey scale confidence intervals. Other than moving to LaTex, does anyone have other

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

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.

Hi all, I'm having a problem creating png images with trellis.device. I would like to create many plots with a white background using a sequence number in the file argument (i.e. "%02d"). The first plot is as expected with a white background. However, the second and all subsequent plots have a gray background. I would like all plots to have a white (or transparent)

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 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

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",

I am having trouble showing the Greek symbol "beta" correctly in the y-axis label of bitmap plots. Specifically, on my system the top of the "beta" symbol is cut off using the following example: file.jpg <- paste(tempfile(), ".jpg", sep = "") jpeg(file.jpg, h = 3, w = 3, units = "in", res = 300, type = "Xlib") boxplot(rnorm(10),

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")

Thanks in advance for the help. Trying to run a basic dotplot in lattice from R command line. When the file is created, in Fedora, it is blank image (jpeg, bmp, png). Image produces correctly in Windows environment. Libraries lattice and latticeExtra are loaded.

Hello all: After I compile the R-1.7 with the follows in Linux7.3: configure --with-x --with-jpeglib --with-libpng --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib and make and make install. The R is able to generate PNG/JPEG files from the command line. However, when I put the same commands in a batch file and run: R --gui BATCH R.Batch.file It gave me a error in the
