similar to: identify() seg.faults (PR#4057)

Hola! I will want to identify pixels in an image with the mouse, for so getting the image data from the matrix(es), for use in subsequent discriminant analysis. But the following bombs R: (windows XP, rw1071) > str(baboon) list() - attr(*, "size")= int [1:2] 512 512 - attr(*, "cellres")= num [1:2] 1 1 - attr(*, "bbox")= num [1:4] 0 0 512 512 - attr(*,

Dear list, here is a problem I met when trying to use a method for an S4 object, without loading the package in which the method was defined. I do not know if this is a bug, or a mistake of mine. Normally, I think the package in which the appropriate method is defined is loaded automatically when calling the method. The problem is that if the package is indeed loaded automatically, the

Hi All, I have a greyscale image that I am reading in through RGDAL and placing in a pixmap object. As an example use the logo.jpg file that comes with the RGDAL package: #Read the file logo <- system.file("pictures/logo.jpg", package="rgdal")[1] x <- new("GDALReadOnlyDataset", logo) #Create the pixmap object xGrey <- getPixmapGDAL(x) Now I would

Hi I need to overlay two pixmaps (library (pixmap)). One, a pixmapGrey, is the basis, and on this I need to overlay a pixmapIndexed, BUT: the pixmapIndexed has set only some of its "pixels" to an indexed color, many of its pixels should not cover the basis pixmapGrey pixel, means, for this "in pixmapIndexed not defined pixels" it should be transparent. What would you

Hi, I'm having trouble writing .pnm images which I think is due to a problem with my colour space. The pixmap object seems to be looking for 72 of 8 colours (one per cell?) which doesn't seem healthy... > library(pixmap) > x <- pixmapIndexed(rep(1:8, 9), nrow=6, col=rainbow(8)) > x Pixmap image Type : pixmapIndexed Size : 6x12 Resolution : 1x1

Hi, I ran into the following peculiarity involving S4 method dispatch and namespaces. I develop a package which have a namespace and which depends on 'pixmap' package, which itself does not have a namespace. Now, in my package I have a class which has a slot for objects from class "pixmap" and I want to have a "plot" method for this new class. Not to clutter the

Dear R users I have a two-dimensional array, whose values I want to plot, using the pixmapGrey class. Plotting works fine, and now I would like to be able to identify some of the points in the plot using identify(). But I get the following message while pressing the left mouse button: > plot(pixmapGrey(fmri.vtc[,,slice,volume])) > identify(fmri.vtc[,,slice,volume]) warning: no point with

In R-beta (Masked Marvel), when I do the example from the read.pnm help file, this is what happens: x <- read.pnm(system.file("pictures/logo.pgm",package="pixmap")[1]) Warning message: In rep(cellres, length=2): x is NULL so the result will be NULL In R-2.15.3, it's all right. Thanks, Erin Erin M. Hodgess, Ph.D. Associate Professor Department of Computer and

Hi R users: I got the following message when I use the pixmap library on R 1.7.0 over w2K platform (on R 1.6.2 it runs right). pixmapGrey(matrix(c(0,1),128,128)) Error in .class1(object) : Object "from" not found I download the library .zip file from: http://cran.r-project.org/bin/windows/contrib/1.7/pixmap_0.3-2.zip Other question: When I try to "Install package(s) from

Hi, my name is Ellen. I want to ask you about R Code. I got a code for extracting a pixel value, but I can't compile it..  It is said "Error in is.data.frame(x) : object 'lena' not found" Here is the original full code: library(pixmap) lena <- read.pnm("oldlennablur.pgm") write.table(lena@grey,"mylenna", quote=FALSE, row.names = FALSE, col.names=

Yes unfortunately I do not have much luck recieving help from the SAMBA mailing list. After much playing I found something weird that was seemingly causing incorrect comments. Most printers would recieve the comment - "no entries" which originally I assumed to be the default comment given by Win95 when it could not get a proper comment. However I later found that this is not the case.

Dear R People: I am trying to replicate a cool example that I saw on the R-bloggers some time ago by kafka399. Here are the lines tI think may be causing the trouble: gray_file <- read.pnm(path) pos[i,] <- c(gray_file@grey) The warning error that I get is "In rep(cellres, length=2): x is NULL so the result will be NULL Any suggestions would be much appreciated. Thanks,

I suppose everybody who makes a package for the first time thinks "I can change anything!" and then runs into this same question. Has anybody written out information on how a package can override functions in R base in the R 2.14 (mandatory NAMESPACE era)? Suppose I want to alphabetize variables in a summary.data.frame, or return the standard deviation with the mean in summary output.

Hello, On FreeBSD, Dovecot 2.0.1 compiles fine with gcc45 and the other services have no problem, but even without any optimizations (CFLAGS) at all, pop3-login seg faults when a user tries to connect to Dovecot using POP3. As this is not the only application that has a problem with the latest version of gcc (mod_php), there may be nothing that can be done on the Dovecot side, but I thought I
