Hi, I installed biOps on my XP, and installed the required dll packages, jpeg62.dll, libfftw3-3.dll, and libtiff3.dll, as suggested by this forum. Then it worked perfectly for about one week till this afternoon. When I tried to load biOps again, I got the following error message again Error in inDL(x, as.logical(local)...

I have tried several times to load biOps package after reading the posts in this archive regarding the necessity of placing these two libs in the PATH (libjpeg62.dll and libtiff3.dll). I have tried locating the libs in several directories that should have worked, but I still get the following message. ------------------ Error in...

I installed the (binary) biOps package, which can use libtiff and libfftw. Then I used macports to install the libraries (in /opt/local/lib). But I restart R and biOps still does not see the libraries. I've tried adding symbolic links from /opt/local/lib to /usr/local/lib, I've added /opt/local/lib to LIBRARY_PATH, LD_L...

All, the MacOSX binary build of the biOps package is broken on cran, so I am trying to compile from source. I am very close; the trick is apparently that this package depends on fftw3, libjpeg and libtiff. My fftw3 is in /usr/local/, but my libjpeg and libtiff are in /opt/local/ since i got them through macports. In general, I'd like t...

Dear All, I found this nice example of PCA application on the web http://www.r-bloggers.com/principal-components-and-image-reconstruction/ and wanted to reproduce the results for myself. I installed biOps the usual way and got the message *package 'biOps' successfully unpacked and MD5 sums checked* but when loading the package, I get *Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library 'C:/PROGRA~1/R/R-210~1.1/library/biOps/libs/biOps.dll': Lo...

Buenas dias a tod@s, Quisiera saber 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

Hello, I'm running R with windows. Could anybody help me how to install the package biOps (http://cran.mirroring.de/src/contrib/Descriptions/biOps.html) ? I cannot find it at any mirror provided by the GUI; I just found it as "tar.gz" which cannot be installed with the installation method... Maybe, I simply do something wrong? Thanks for any hint! Antje

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]]

...our, through checking eye movement. The point is this is very important to get data from the image as a resume of what this animal sees. I think an RGB histogram like photoshop does, but I need to get the data from this histogram analysis and I was wondering about using R to do so. I have check the biOps-package, but it does not work in windows 7. So, someone knows if there is some special package about image analysis.  It would be really appreciated. I have never heard about image reseach like this. I think some geostatistical image package could help, but I have not idea. Thank you in advance. J...

I am not sure if I should ask this question in this list. But I'll try. Currently I am trying to analyze images using EBImage and biOps. One of the features that I need to extract from various images is the color spectrum, namely, which colors each image consists of. So, each image hopefully can be converted into some sort of color histogram so that color ingredients are easily comparable with each other. There are so many functi...

Can someone advise me what the most sensible way is to read jpeg images? For our work with image analysis and eye-tracking we have been using the rimage package, on both Macs 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

Hi al, I have a dataset (see attached), which basically involves 4 treatments for a chemotherapy drug. Samples were taken from 2 biopsy locations, and biopsy were taken at 2 time points. So each subject has 4 data points (from 2 biopsy locations and 2 time points). The objective is to study treatment difference.? I used lme to fit a mixed model that uses "biopsy.site nested within pid" as a random term, and used corAR1(...
