Hello, I've looked in tools:::.install_packages for some sort of hook that would let packages developers point to further instructions after a package is installed. For example, some packages need to setup environment variables, ... Is there something I have missed ?

Folks, In brief -- how many of you have found the 'operators' package to be valuable in their work? Not that I lack respect for the amount of work involved in creating and maintaining a package, but I am unsure about the utility of these new operators. Several of the operators appear to offer different ways of accomplishing tasks that are already relatively easy in base R -- regular

I am out of my league with this question. The following code starts the java imaging program ImageJ from within R, and displays an image (assuming ImageJ is installed on your computer). library(RImageJ) img <- IJ$openImage( file.choose() ) #pick an available .tif file img$show() # make the image object visible # An image is now displayed # find out about the objects involved >

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 ?

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've uploaded the initial release (0.0-142) of the RImageJ package to CRAN. The package allows R to use the facilities of the java based image processing and analysis platform ImageJ. See also the announcement on my blog, with a very simple example showing how to use the package: http://romainfrancois.blog.free.fr/index.php?post/2009/06/22/using-ImageJ-from-R%3A-the-RImageJ-package

Hi, Maybe this is more a programming questions than a specific R-project question, but maybe there is someone who can point me in the right direction. I have a picture of cirkels which I took with a digital camera. Now I want to use the diameter of the cirkels on the picture for analysis in R. I can use pixmap to import the picture, but how do I find the outside cirkels and calculate the

Hi, I'm trying to use the data which I generate within R to make images in .bmp format to be lateron printed by a printer. My first thought was the RImageJ package, but this seems to be discontinued. What I am currently doing is generating a matrix of grey values, which needs to be parsed into the right image format. Is anyone aware of a package or rather "easy" way to generate

Hello everybody, I'm running R under Mac OS 10.6.3 on a MacBook 2.16 GHz Intel Core 2 Duo. I've recently installed R 2.11.0 and the RImageJ library v. 0.1-142. When trying to follow the example given in the package manual and I get the following error: download.file( "http://www.google.fr/intl/en_en/images/logo.gif", dest = "google.gif" ) trying URL

I have some images of bugs (insects) with many bugs in each image. I want to count the number of bugs and to have an estimate of the area of each one. I've tried searching for an R package to do so with no success. Is this a task that I should pursue doing in R or should I restrict myself to specific image analysis software (e.g. ImageJ)?. The reason I consider R would be a good choice is

Dear all I tried to find some packages (or programs) for image analysis and especially fractal dimension image analysis but so far I had not success. It shall be used for particle surface layer analysis from TEM images. Any suggestions? Best regards Petr

What software exists for digitizing video to quantify the motion of specific features in the image? I might be willing to use something that's NOT in R, though I'd prefer something in R (or at least with an R intereface). Thanks, Spencer Graves

Hi Folks, I am creating a multi-threaded C++ application that initializes RInside in one of the child thread. I would also like to access support interfaces like Rcpp::Environment in the remaining child threads, so that I could access any "R" function associated with the environment initialized. When I run my program, I always get "C Stack limit too huge" errors. I looked

In response to an earlier discussion about finding the fastest/best/nearest CRAN site, I geocoded (using my geonames package) the locations of the CRAN sites returned by getCRANmirrors. I've mapped them here: http://www.maths.lancs.ac.uk/~rowlings/R/Cranography/ The geocoding may have got it wrong, so if CRAN site maintainers want to send me a real lat-long (in WGS 84 aka EPSG:4326) I'll

Hi, I am using the R-2.9.1 with Window XP. Queries: 1. I am running the java application which needs to load property file in R. So can you please tell me how I can load my property file in R session so that my application can find that property file? Attached is my property file for sample. 2. Is there any directory structure required for java

Dear R-helpers, does anyone know of some package/function that can build a network from the functions that are implemented in a package, i.e. visualize the cross-references from one function to another in the same or some dependent package? An example would be a function like 'nls' on top of the hierarchy and then a network of nodes from the functions that are called within 'nls'

Hi r-devel, svSocket is working well. Short demo here of using it with data.table : http://www.youtube.com/watch?v=rvT8XThGA8o If you maximise and press the HD button it should be readable. There isn't any audio. However, svSocket is currently text based IPC using dump. Is there a solution which will do binary and work in the same way ? Its nice that I can make R become a server any
