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 ** building package ind...

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 'C:/Programs/R/Cran/EBImage/libs/EBImage.dll': LoadLibrary failure: The specified module could not be found.

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/q...

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"...

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 Files\\ImageMagick-6.6.1-Q16;C:\\GTK\\bin;C:\\WINDOWS\\syste...

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 'C:/PROGRA~1/R/R-2.7.1pat/library/Ca...

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 [...

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: x[i,,] and x[i] with the former returning a 2D array of values and the latter returning a single val...

Dear all, Following a suggestion by Henrik Bengtsson I installed EBImage/biocondutor package. I also installed ImageMagick and GTK software because EBImage need it. After look at EBImage I find a function that compute Haralick texture on images. I tryed to run it with following simulated image, but I get error. myimage<-as.Image(matrix(sample(100*100),nc=100)) imag...

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]]

...ns on array-like objects of any dimensionality. The package is centred around a flexible function called morph(), which can apply any kernel to array elements, optionally conditioned on their value or number of nonzero neighbours. Operations such as erode and dilate are provided for 2D data by the EBImage Bioconductor package, but mmand can be used for higher (and lower!) dimensional data, can produce and apply anisotropic kernels, and does not have external dependencies--except for the small, pure R package "reportr" (also on CRAN), which is used for message reporting. Owing to its more...

Dear R users, In last R News, a new package was appeared. EBimage image processing package seems so powerful. But in R News, it is used for the images of cells under microscope. So, i wonder whether there is anyone who use this package for materials science applications such as determination of mean diameter of particles, fibers or pores, estimation of porosity...

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 ? Thanks, - Martial _________________________________________________________________ Tchattez en direct en en vidéo avec vos amis ! [[alternative HTML version deleted]]

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 = FAL...

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(i...

...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, i.e. a 3D R-array of numerics for the purpose of this code. LENGTH(x) can be up to 1e6 and the number of elements potentially to be in the queue is about 20% of those. But I get segfaults often on a third of fours element being added. Tried on R2.5.0-devel, R2.4.1-release and all machines we...

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.
