Hello All I have just tried to install the ReadImages packge in R but am getting an error message stating: "This application has failedt to start because jpeg62.dll was not found. Re-installing the application may fix this problem" and at the R prompt this error message gets returned: > local({pkg <- select.list(sort(.packages(all....

...malous white line running across the picture (either horizontally or vertically). The line can be removed by simply stretching the image frame a little in the direction perpendicular to the anomalous line, or by maximizing the image frame (tested under Fedora 10; Windows could not be tested because ReadImages package does not load properly under Windows/Vista, and rimage is not available for Windows). It does not help to use x11(width=10,hight=10) before the call to image() with the hope that the frame will already be large enough: image() just draws a larger image with an anomalous white line (which c...

Dear all I prepared some image processing routine which depended on package ReadImages. Basically I imported image to R, changed rgb to grayscale, normalised an image made some selections and changed to image by imagematrix. Recently I learned that this package was removed from CRAN and can not be used in R 3.0.0. What options I have now to import image to R, change it to grayscale...

...ber si alguien tiene experiencia con el procesamiento de imágenes (en formatos JPEG o PNG) en R y la búsqueda de similitudes / diferencias entre ellas. La idea de lo que me gustaría hacer es: tomar una imagen, cargarla en R y luego analizar su estructura. Para las dos primeras tareas, la libreria ReadImages en CRAN me ha sido útil, pero para la segunda, hasta ahora no he encontrado ninguna aplicación. Este es un ejemplo tomado de la libreria que menciono: # install.packages("ReadImages") require(ReadImages) data(logo) par(mfrow = c(1,2) ) plot(logo, main = ''R-logo, formato origina...

Dear all, I am looking for a function that can read a simple bmp file and return me a matrix with their corresponding values. I have already looked in the packages require(ReadImages) require(pixmap) and also did apropos("image") but I could not find something that can do something like that. I have also tried the read.ftable but it also failed. B.R Alex [[alternative HTML version deleted]]

...and Windows PCs. But while setting up a new Windows machine yesterday, I see that rimage is regarded as orphaned, and no Windows binary is available. I eventually found an old zip file for the package, so I am not stuck, but I wonder what the right way is to go forward. I did find the readimages package, but it also seemed problematic to install on both Windows on Mac, requiring extra software that it was itself unclear how to install. Is there some simpler solution I should be looking at? Are jpeg files so probematic I should be converting them to some other format and us...

...files in this package, and AFAICS, every example uses library or require for the functions used; the DESCRIPTION file has the long list of Suggests, which previously was sufficient for packages used in examples. Suggests: gtools, KernSmooth, maps, ggplot2, proto, grid, reshape, plyr, lattice, ReadImages, car But I have no way to find the .Rd file(s) that triggered this note. What is the tool used in R CMD check to make this diagnosis? It would be better if this reported the .Rd file(s) that triggered this note. Is it possible that this note could be specious? -Michael -- Michael Friendly...

Dear list members, I need to translate 3 lines of matlab code to R (a loop, to be specific), and I don't know what would be the results in matlab or how to do it in R-- I don't realise if they are doing to the col, vector or what. if the results are a vector or a value or a matrix :-( Anyone with matlab, can run it and give me the result? Any ideias what am I doing wrong? The code is

Hello I wanted to compare two fingerprint images. How do you do with R?. Is there a role for cross-correlation of images?

Dear all, I'm pleased to announce the release on CRAN of the "mmand" package (for Mathematical Morphology in Any Number of Dimensions). It provides functions for performing mathematical morphology (erode, dilate, etc.), smoothing, and other kernel-based operations on array-like objects of any dimensionality. The package is centred around a flexible function called morph(), which can

Hi all, I know that I can for instance draw to plots in one using nf<-layout(matrix(c(1,2),1,2,byrow=FALSE)) Imagine I have 3 files: plot1.jpeg plot2.jpeg plot3.jpeg Anyone knows if I can read them and put on one colum and three rows reading directly from the jpeg file? Many Thanks [[alternative HTML version deleted]]

The question is how to use a URL in place of a file= argument for read.*.functions that do not support this internally. e.g., utils::read.table() and her family all support a file= argument that can take a URL equally well as a local file. So, if I have a file on the web, I can equally well do > langren <- read.csv("langrens.csv", header=TRUE) > langren <-
