Dear all, I have written a small set of functions for drawing graphical representations of R objects and evaluations of R expressions. It is mainly intended for pedagogical purposes. Here are some samples: http://panini.u-paris10.fr/~sloiseau/sampleGraphics.pdf The idea is to use some graphical conventions in order to make clear the abstract syntax and to explain function, extraction,

Hello, I'm looking for a way of mesuring the adequation of a given variable with the normal distribution. Does R provide a standard test for this purpose, or is there a statistical methodology? Best, Sylvain Loiseau

Hola, ¿qué tal? No sé si alguien tiene experiencia en llamar a R desde Java. Estoy desarrollando una aplicación en Java que realiza varias llamadas a R. Me gustaría poder capturar el "device" donde R dibuja su salida directamente en el GUI que diseño con Java (sin guardar el fichero .png, cargarlo desde Java, etc.). ¿Alguien se ha enfrentado antes con este problema? No he visto

Hi 2 questions- 1. Is there a package that will allow me to run R scripts (entirely) from Java? 2. If so, is there a way to capture the output of those scripts, (including images) and embed them in my SWT java app? My challenge is I have a java app that does some statistical chores- it would be fantastic if the users could use their R skills to modify a script in whatever R environment they like

Hello, I am interesting in using R from a web application, for basic statistics and plots. The server is Java-based (tomcat). The simplest solution is a system call that generates the text or the image, then the servlet forwards the output. This can be done from any language, but it is quite inelegant and slow for the initialization time. Is there any package or approach for accessing R from a

Has anyone come across any alternatives to rJava and JRI? Are they any good? Better perhaps? Please give your reasons.

Dear all, I'm facing a strange behavior in the the C code of a R package. This package, "rcqp", is a wrapper on an existing program that I did not write, "CWB". In this package, on a linux (ubuntu and debian) system, the code : printf(%d\n", isupper('A')); outputs : 0 When compiled with the R framework (It behaves correctly when CWB is compiled as a

Dear all, I have been writing during last year at the European Bioinformatics Institute a general unified open source solution for R integration. This work is now available via this link: http://www.ebi.ac.uk/microarray-srv/frontendapp/ The different frameworks and tools of the biocep project are now robust enough for production use. The different APIs are finalized but the documentation is

Hello, Earlier I posted a question about memory usage, and the community's input was very helpful. However, I'm now extending my dataset (which I use when running a regression using lm). As a result, I am continuing to run into problems with memory usage, and I believe I need to shift to implementing the analysis on a different system.. I know that R supports R servers through

Hola, es la primera vez que mando un correo a cualquiera de las listas de correo de R y no se si esta consulta se ajusta al próposito de la r-help list o debería haberlo mandado a otra de las listas que hay. Mi problema es el siguiente: Estoy desarrollando un programa en java con llamadas a R y no puedo usar jri 0.4-1 con la version 2.7 o 2.6 de R. Curiosamente si me funciona si uso jri 0.4 o la

I have posted this message on r-lang, but it is perhaps more appropriate on r-devel: --- Hello, I'm puzzled by a problem with call to diag(), rowSums(), rownames() on objects of class "dgtMatrix", created by sparseMatrix() or spMatrix(). I use Matrix 0.999375-30. The weird thing is that I don't encounter any problem when I use this functions on the R prompt, or

Dear R-Help, I am trying to get JRI (the rJava interface allowing Java to connect to R) to work. I was able to run it a week ago when I was doing some testing using Java 1.5. However, I am developing a GUI application using some of the new Java 1.6 features and I just can't get JRI to work with this setup. Here is what I get: Cannot find JRI native library! Please make sure that the JRI

Hi all, I am writing R code and I want to interface with JAVA i.e. I want to call R from JAVA. That's why i have installed JRI on my machine. There is also documentation available in "Javadoc".

Hello All I am trying to get the JRI examples from rJava to work on Windows XP and failing. (And as a more general and connected question is there any review/summary of front-end software for R?) I have installed rJava from the Windows binary supplied. I compile and run the example supplied (rtest.java) and get the results below. I do not think the notes about a deprecated API are a problem. But

Hello, I am a new R user. More precisely, I am working with JRI (on a Eclipse Java6 project under Ubuntu9). I have difficulties to access some R packages (For example: package "stats", object "Normal", function "pnorm"). I have tried many solutions to set the right path but nothing have succeed: For example:

Hi, I want to call R from within Java, using jri as per http://www.rosuda.org/software/jri/ So I am following the instructions in the README file for JRI 0.2-4. I have run 'sh configure.win' and 'make' and they seemed to be successful. (See below for the output from make, for example.) But when I try 'run.bat rtest' (with and without R command line arguments) the output

Dear all, In a new package, I try to check the examples given in the \example section of the Rd files. However, the examples cannot be run if the package is not instructed, during startup time, in the place where some data are to be found ( with system.file("exampleData", "xyz", package="rcqp"). Is there any hook available, or a place where some code might be

Hi, I need your help. I have downloaded a precompiled JRI as part of rJava. I have included rJava as part of my R package libraries. Now I need to be able to work with some R functions from my Java apps. I'm using NetBeans on Windows.
