similar to: stop R mainloop without calling exit(1)

Dear r-helpers, I have been trying to invoke R from Java in a Windows 2000 computer (unfortunately). All my environment variables seem to be properly set, everything seems to be in order, but I obtaining a Fatal error: unable to open the base package error window. Also, the output of the invoker is Loading RInterpreter library R_HOME: R_HOME=C:/Programas/R RVersion: R_VERSION=1.6.1 whereas

i'd like to use the C interface to R in a program i'm writing. as a starting point, i'm trying to create a very simple C program that uses R. i've read the R documentation on this, but i'm having trouble figuring out where SEXP is defined and how to use it. i noticed someone else on this list also tried to use the C interface, but they ran into similar problems:

R-0.64.2 and R-devel: [I found this by looking at the code.] A .Last function is _only_ called if the condition that causes termination is EOF on the console or input: > .Last <- function() cat("ran .Last\n") > q("no") returns to the shell. > .Last <- function() cat("ran .Last\n") > # I hit ^D here ran .Last Save workspace image?

The call to system() probably is an internal call used to delete the session's tempdir(). This sort of failure means that a potentially large amount of disk space is not being recovered when R is done. Perhaps R_CleanTempDir() could call R_unlink() instead of having a subprocess call 'rm -rf ...'. Then it could also issue a specific warning if it was impossible to delete all of

Hi All My C++/linux program uses Rf_initEmbeddedR to start R and then calls some R functions. Now I try to port it to Windows. Give the fact that Rf_initEmbeddedR is missing in Windows, I try to use the implmentation in Rserve by Simon Urbanek. When I build in MS Visual Studio, I get the following linking error error LNK2019: unresolved external symbol __imp__putenv referenced in function

Dear list, I am trying to implement a publish-subscribe mechanism in for an embedded R interpreter. But somehow my registered closures seem to get collected by the GC, even though I have protected them. I have reducted my code to the following sample. Sorry if it is a little verbose. The first couple of call of calls still work, but at some point one of the callbacks (callback1 in my

Dear R developers, i've got a question concerning an embedded R instance. I called the initialization routines as seen in the "writing extensions" guide (Rf_initialize, setup_Rmainloop and R_ReplDLLinit). I also changed the function callback pointer of readconsole and writeconsoleex to my local functions. when i call mainloop there is no problem and the commands are evaluated

I'm searching for answers to four questions (I've been searching the net for hours...) In Windows XP, is it possible to call R functions from a c program? (I've found examples for Linux/Unix but not Windows) If so, is there a simple example to get started using gcc with R-2.10.0? If so, is it possible to write a simple interface using a c dll to call R functions from a Visual

I have got now Redhat 7.0 and when I want to install Swat I need to edit the file /etc/inetd.conf but in Redhat 7.0 the file is named to /etc/xinetd.conf and /etc/xinetd.d can you help me ?

Thanks Bill for checking that. It was my impression that warnings are raised from some internal system calls made when quitting R. At that point I don't have much control over checking the return status of those. Your suggestion looks good to me. Tomas, do you think this could help? could this be implemented?

I'd like someone familiar with the R options initialization to comment on a difference of behavior within/without mpiexec I have a (.NET) application with embedded R that is proven to run in a single process: ./Sample1.exe on a Debian Linux with R 3.0.2 Running the same code with mpiexec, it fails at the R engine initialization: mpiexec -n 1 ./Sample1.exe Fatal error: you must

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

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". But as i am very new to JAVA and well as R, I don't understand much of it. If someone is using this package i.e. JRI, please let me know whether i am going in right direction or not.

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:
