Dear Sir/Madam, I am using R-Image in an MSc statistics dissertation and have found, in various EBImage manuals a functions - bwimage, which I would like to use, however I can't find it within my version of R. Could you tell me if the function has changed or what I need to do to be able to use it. Many thanks Alice [[alternative HTML version deleted]]

Hi, on a lattice, I have binary 0/1 data. 1s are rare and may form clusters. I would like to know the size/length of largest cluster. Any help warmly welcome, Sylvain.

Hello, I've been having some trouble working with the aroma package and have realized that it's my ebimage is at the root of the problem. The package builds but during testing it fails because of an undefined symbol as seen below: installing to /usr/local/lib64/R/library/EBImage/libs ** R ** inst ** preparing package for lazy loading ** help *** installing help indices **

Hello, Working with Windows 7 in a HP laptop with R-2.10.1 I download and installed ImageMagick-6.3.7.7-Q16-Windows-dll.exe and GTK 2.12.9-win32-2, then downloaded and installed from local file EBImage_3.2.0.zip and I got: > library(EBImage) Loading required package: abind Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library

Hi, I have an S4 class directly derived from 'array' as shown in the code below (EBImage package of Bioconductor 2.1, devel), it simply contains array adding a couple of slots: setClass ("Image", representation (colormode="integer", filename="character", compression="character", resolution="numeric", features="list" ),

Hello all I've just spent a few joyless hours trying to get EBImage to install in R. I'm running Ubuntu (Hardy Heron), fully updated (including R and Imagemagick). EBImage installation seems to work, but when I 'library(EBImage)' I get the following: - - - - Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/home/qilin/R/i486-pc-linux-

Hi, on Windows XP Pro with R version 2.7.1 Patched (2008-06-27 r46012) the 'Cairo' and the 'EBImage' packages does not play well together. Loading EBImage before Cairo cause the following to happen: # Rterm --vanilla > library(EBImage); > library(Cairo) Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library

Dear All, Consider a matrix (N x N) where each entry is either zero or one (can hardly get any simpler). Now, I would like to plot it as a 'chessboard' where every matrix entry is a black (1) or white (0) square. Whatever tool I use to plot it, it should not try to interpolate the data at all. I found some online references http://www.phaget4.org/R/image_matrix.html but probably I can

Hi group, I've spent half a day trying to figure this out and searched through different forums. I've tried to load EBImage but am getting the following problem: >Error in inDL(x, as.logical(local), as.logical(now), ...) : > cannot initialize ImageMagick >Error: package/namespace load failed for 'EBImage' My path is like this: C:\\Program

Hi, I am working on writing some S4 classes that represent multidimensional (brain) image data. I would like these classes to support standard array indexing. I have been studying the Matrix and EBImage (http://www.bioconductor.org/packages/1.9/bioc/html/EBImage.html) packages to see how this is done. When using objects of the "array" class directly, R distinguishes between the calls:

Hi, I am looking for a R package which is capable to process and analysis pictures of tissues (stained) in an automatic way. I had a look on biops and EBImage (Bioconductor) but they are not automatic... Did you already use/know a such package ?

I am having trouble using the "resize" function (in the package EBImage) with matrices containing double values. Let's say I have a matrix 'b' with these values:   > a = c(1.25,1.555,1.245,1.265,1.656,1.235,1.848,1.959,1.548,1.245454,1.989,1.24) > b = matrix(a,4,3) > b       [,1]  [,2]     [,3] [1,] 1.250 1.656 1.548000 [2,] 1.555 1.235 1.245454 [3,] 1.245 1.848

Hi, all. I searched a lot at mailing list, installed EBImage and gtk packages, but I couldn't make this simple work: How to add a image file (jpg or bmp ou gif) to an existing plot window (not plot over the image), like the code below (pseudo function add.image): plot(1:10,1:10,main="test") image = read.X("myimage.jpg") add.image(image, x.left=2, y.bottom=4,

Dear lists: I am somewhat puzzled by the use of texi2dvi/pdflatex in R2.7.0. When building EBImage (bioconductor) with 2.7.0 I get the same error both in Windows and Linux, which reads the following: ** building package indices ... * DONE (EBImage) * creating vignettes ... ERROR /usr/bin/texi2dvi: pdflatex exited with bad status, quitting. Error in texi2dvi(file = bft, pdf = TRUE, clean =

Hello, is there any one who uses C++ STL classes when programming shared libs for R and has had any problems with STL? In the very simple example below I am constantly getting segfaults when trying to populate the queue. The segfault occurs at what looks like a random index in the loop when pushing another element to the queue. Reproduced on 4 machines. Object x is an Image as in EBImage,

Hello all, has someone please a few hints about how to 1.st: draw an image (preferrably a jpg) and then 2nd: plot() on that image I am using a mac - and after searching and trying different ways (I have installed EBImage) I now would like to ask for help... Thanks! Johann

Hi, I am using the EBImage package for image display and analysis and want to read the cursor (mouse) position on the image. The function "locator()" would be ideal, but this appears to work only on plots, not images. > a <- Image((0:(w^2))/w^2, c(w,w)) > if ( interactive() ) display(a) > locator(n = 10, type = "p") Error in locator(n = 10, type = "p")

Hi, We have recently been using the tiff package for reading tiff images into the Bioconductor Package EBImage. This has been extremely helpful in conjunction with other steps to eliminate dependencies on ImageMagick. However, it seems that 12-bit images are not supported. We were wondering if there are plans to extend the functionality of the readTIFF() function in the tiff package to

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.

Is it possible to plot an image (currently a jpeg) in the margins? Thanks, Kari [[alternative HTML version deleted]]
