similar to: gray background on jpegs using dev.print()

Hello, I have the following question, which I haven't been able to resolve after days of trying. I used to save my plots as jpegs using the savePlot command. However, that seems to result in lost resolution. So now I'm trying to use the jpeg( ) function, but am having trouble because it seems to be incompatible with the windows (width=, height=) command. It's important for me to

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)

Dear useRs, When I use coplot() and output to png/jpeg/bmp, the grid lines from the scatter plots disappear. If I output to pdf() the grid lines are there, however I can't use it - I have many points, and the resulting PDF file is large and very slow to open and scroll through. (By the way, if I click File-Save As-png/jpeg/bmp from Rgui.exe, the grid lines are preserved - but I need to use

Hi, I'm trying to make a png file of a histogram. I would like a white background in the final product but end up producing a gray one, despite setting what I think are the correct parameters. Suggestions for how to properly set a white background would be welcome. Thanks in advance, Scot # for non-lattice > par("bg"="white") > par("bg") [1]

Hi, I try to create PNG images of a certain size where each pixel intensity corresponds to exactly one probe signal in an Affymetrix array. I try to use png() and image() with zero margins to do this. Example: z <- matrix(1:15, nrow=45, ncol=30) png("large.png", height=nrow(z), width=ncol(z), bg="red") par(mar=c(0,0,0,0)) image(z, col=gray.colors(16), axes=FALSE)

Hi, This may be an easy question, but let me ask it. When writing a plot to a jpeg file: > plot(runif(30)) > dev.print(file="test.jpeg", device=jpeg, width=600) the plot I receive has gray background, the result on no account I want to receive. The same situation occurs when printing to a bmp file. But when printing a pdf file, the background is white as it should be. What

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.

Thanks to Edzer and Roger, I can now plot with increased font sizes. However, jpeg still does not reproduce these, nor does it show up in high quality. What I would like to do is produce some highresolution jpegs. Any help would be appreciated Thanx Herry R2.4 on Mandriva 10.2 linux.

Hi all, I'm running the following code to generate 40 different jpegs based on the resulting data. I'd like the file names to be 'Cluster1.jpeg', however the code write filenames like 'Cluster 1 .jpeg'. How can I get rid of the unwanted spaces? I've looked at ?format and it doesn't seem to work - at least in this context. ################### ClusCount <- 40

Appologies if this has been addressed before, but I can't seem to find it in the help archives. I'm looking to do something like the following but it looks like save.plot is deprecated. save.plot(plot(glm1$residuals,gain,main = "Hist of residuals and gain"),file="Desktop/hist1.png") Thanks in advance, Sean Session Info: R version 2.9.1 (2009-06-26)

hi all I guess that *Theora* will convert the input color space (RGB or CMYK or any) into YUV before it process and encode. (that means theora can operate on several color space, but it get convert into YUV before process) Is that true...? I want to get a gray scale, encoded video output from the *Theora* encoder while the input video is getting from a web cam (color input and gray scale

Hi, I am working with QCC and would like help with the following: a) Change the color of the background. I tried bg="#FFFFFF" in par and also in qcc and it did not work. b) I want to remove the X Axis Text (i.e. 1, 2, 3 ... n) -- but xaxt="n" does not work in qcc.

I've been attempting to export a graphics file of my lattice plots and no matter what color I use for the bg= argument in the bmp/jpeg/png function, the background is grey. bmp(filename = "c:/my_paper/resids.bmp", width=1024, height=1024, pointsize=10, bg="transparent") # these are lattice plots. plot them in a 3x2 matrix print( hgqqplot, position=c(0.0, 0.66, 0.5, 1.0 ),

Hi the list, I used savePlot to export some eps graph but it seems that the graph file hold a bug. I include the graph.eps in a LaTeX file. Running latex is ok. But the dvi file contain some mistake, the graph overprint on some text and hide it. Then, when I try to convert it to another format, I get : Ignoring remaining special text following unkown PS operator: "SDict" Remainder

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

I have a linux system with Fedora Core 2 and R-2.0. I was comparing plots made with plot() and dotplot() and discovered a problem. Although the dots are positioned correctly, the numerical labels in the dotplot y axis are not correct. I put copies here: http://lark.cc.ku.edu/~pauljohn/R/plotTrouble1.jpg That is the "correct" one from plot, with the higest value on y showing at 18.

I downloaded the iid.test, but I can't run it. I get the following message: Error: could not find function "iid.test" Where am I supposed to save this package in order that it works? Thanks, EZ [[alternative HTML version deleted]]

Hi everyone. I am new to R. It will be greatly appreciated if someone can help me with the following questions. Here's the graph I have just produced. http://www.nabble.com/file/p24732839/calibration.jpeg (1) How can I put the legend on top of the grid lines? (2) How can I match the grid lines with the x-axis ticks? (3) How can I change the x-axis format from e.g. Mar, Apr...etc to

Hi all, I've written some code to generate 4 maps per screen and write the output to a jpeg. The output is fairly quick at the start (about 5 jpegs per minute) and then slows down greatly (1-2 jpegs per minute). Is there some way to speed it up? One of my thoughts is to keep the base map static on the screen and just update the points that are being plotted on the map (with the exception

Dear all I have trouble with setting the size for jpegs and pngs. I need to save a dendrogram of 1000 words into a jpeg or png file. On one of my computers, the following works just fine: bb<-agnes(aa, method="ward") jpeg("C:/Temp/test.txt", width=17000, height=2000) plot(bb) dev.off() On my main computer, however, this doesn't work: >
