Most used R editors
Hi,
I am a little lonely as R users in my group. So, I would like to know which editor is the most used in the R community.
This post is some kind of survey.

- open more than one R session
- split the emacs editor as many part as you want.
- use a lot of keybindings.

I also tried Rkwards, Scilab (windows), JGR etc... but they are not

Hi,
Is there a mean to automatically choose one version of the 'rbind' function ? By default, R chose the 'rbind' from {base}, i would lke to use the one from {IRanges}...
Is it possible to set that using 'par' ?

image color analysis
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

'Dynamic' 3D plot
Hi,
I am looking for a R package to draw 3d plot. But not in a static way like scatterplot3d or stuff like that. I would like to make rotate the plot, to zoom/unzoom etc..., actually to render the graph 'dynamic'... (for the biologist and bioinformatician, a R package which permitts to reproduce what pdb viewer does).
Does a Way exist to do something like that in R ?
Thanks,

Optional libraries (libtiff, etc) not found
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_LIBRARY_PATH, and
DYLD_LIBRARY_PATH, and it doesn't work.

Análisis de imágenes en R
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

Package installation
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!

building biOps on macports, and configure--vars
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 to keep as many of my third-party libraries as I can in the
