Hello, I'm evaluating this expression expression({ for(x in 1:5){ .Call('rh_status','x') }}) a million times from a program with R embedded in it. I have attached reproducible code that crashes with Program received signal SIGSEGV, Segmentation fault. 0x00002b499ca40a6e in R_gc_internal (size_needed=0) at memory.c:1309 1309 FORWARD_NODE(R_PPStack[i]); Current language:

Dear All, I've read the manual on "Writing R Extensions" and in particular the part on calling R from C. (Most of the manual is about calling C from R, not the other way around.) The good news is that I can now call _some_ R from C, specifically the R functions which have C header files. However it isn't clear to me how to call R functions that are written in R. I

Hola buenas, utlimamente estoy teniendo más problemas con mi equipo de los que debería.

I have been futzing around for days tying to get rJava to install on my freshly build Debian Lenny installation. I have R-2.9.1 installed from source in my R_HOME directory and R-2.7.1 installed via apt-get install r-recommended. I was tried many different things, but by accident started up R-2.7.1 as root and viola, successful install. I immediately exited out of R-2.7.1 and started R-2.9.1 as

Hi, I'm trying to understand (mostly from the R-exts manual) how to use the callbacks declared in Rinterface.h. As a first attempt, I'm trying to redefine ptr_R_WriteConsole in a very trivial manner.

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

Hello all, I`m a computer science student from Frankfurt/main (germany). Our student team (10 students) are working on a R/Interface project (Java and R) and we have a problem with R and JRI. We are working on 10 computers with Windows XP SP2, R 2.8.0, jdk1.6.0_11 and the same classpath setttings but our application works only on two computers. We can't explain us this.

Hi, Who should I ask about my package Rigroup_0.83 being moved to Archive status on CRAN and no longer available via install.package? I have no problems with the move if this was simply because of low demand. However, if there was a build issue with the newest releases that caused problems, I would be happy to address it. I'll just ask my students to install it from my own locally hosted

Dear list, I am trying to embed R into a C++ program. After some tinkering, reading the documentation and browsing the source code I have this more or less working. A very very condensed and very simplified version of the code is included below. The program can create plots. However, after the plot is initially drawn it is no longer updated. When scaling or updating the plot the window becomes

Dear R developers, this mail is basically a summary / clarification of some previous mails I sent to this list last week (subject "Catching warning and error output"). Duncan Murdoch pointed out that these were badly organized, and suggested I repost, collecting the main points previously spread out between several mails.

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.

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
