Dear R users, i would like to apply a PCA on image data for data reduction. The image data is available as three matrices for the RGB values. At the moment i use x <- data.frame(R,G,B)#convert image data to data frame pca<-princomp(x,retx = TRUE) This is working so far. >From this results then i want to create a new matrix from the first (second..) principal component. Here i stuck.

Dear R developers, i would like to start R with a *.RData argument under Linux. Something like R -f /home/user/workspace.RData Is this possible?

Estimados erreros, Estoy intentando entender como calcula el paquete dismo ( https://cran.r-project.org/web/packages/dismo/index.html) un coeficiente de variación. Os pongo un ejemplo: tmin <- c(10,12,14,16,18,20,22,21,19,17,15,12) # temperatura mínima media mensual de un año tmax <- tmin + 5 # temperatura máxima media mensual de un año prec <- c(0,2,10,30,80,160,80,20,40,60,20,0)

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

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),

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

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.

Hi, When I want to output a png file, I have the following error message : Error dans X11(paste("jpeg::", quality, ":", filename, sep = ""), width, : inpossible de d?marrer le p?riph?rique JPEG De plus : Warning message: impossible d'ouvrir le fichier JPEG 'Test.jpeg' or in english Error in X11(paste("jpeg::", quality, ":",

Hi, I have some code that uses rJava. One of the Java side methods returns a byte[] representing the bytes from a PNG image. What I'd like to do is to be able to bring up the PNG on the R side (I can bring up a Swing window to show the PNG but I want to avoid that). I have looked at the pixmap and rimage packages but don't seem to be able to work out how I'd go about this (or if

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. However, with the version R-2.3.x with whicc I work , they are available. May be it's a bug, or may be my mandriva 2007 distribution are not all required libraries ? But I have

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. Code: ----------------- jpeg(file = "/tmp/img/temp31.jpg", width = 768, height=768) xy <- dotplot(1:10) print(xy)

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")

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.

When I execute the following code, it works just like I want it to: three pages of nine (or fewer) plots. However, when I execute the code with the first and last lines uncommented, I get three pages (files), but the 2nd & 3rd pages have overlapping plots. It's like a new page wasn't created. I'm pretty sure I've either misplaced or left out a crucial call to some

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,

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
