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-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

Dear all, my aim is to integrate R in an interactive visualisation software called Bulk Analyzer developed by VrVis (http://www.vrvis.at). the code: SEXP e, tmp; ParseStatus status; PROTECT(tmp = mkString("x <- c(1.234,-3.45)")); PrintValue(tmp); PROTECT(e = R_ParseVector(tmp, -1, &status, R_NilValue)); PrintValue(e); UNPROTECT(2); produces the following output: [1] "x

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:

I have a problem to understand the way gc_inhibit_torture is defined. In include/Defn.h it is declared as extern, using the __MAIN__ trick this leads to a definition in main/main.c. But in main/memory.c you define (and initialize) gc_inhibit_torture again: int gc_inhibit_torture = 1; /* gets set to zero after initialisations */ Then, in e.g. unix/system.c immediately at the beginning 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 R-developers, even though I may not be the first one to encounter the problem described below, I would really appreciate some help or a link to a forum where this topic is being discussed. Probably I am simply misinformed on the usage of structRstart but see for youselve. I did check multiple forums and the whole internet on the topic without success. I am using the shared library version

After a long processing, I was able to create a version of a small C# class that was able to emulate the rproxy by P/Invoke. This is mostly to find a workaround a performance problem of the StatConnector. It's almost work but ... I have strange memory exception when I call the print function. The variable seems to not survive from one call to the other. As there is no debug symbol for

After installing the package 'rscproxy' downloaded from the CRAN server, I get the following error message from R 2.8.0 about a version conflict : package 'rscproxy' successfully unpacked and MD5 sums checked The downloaded packages are in C:\Documents and Settings\John Meerman\Local Settings\Temp\RtmpbK9mxN\downloaded_packages updating HTML package

Hi - I wrapped R.dll up using somebody code online (see below). I am comparing R on .NET IPC with R(D)COM. I got it all working. Except, I realize that in my client code of the IPC remoting, if I call 'plot' function in R via EvaluateNoReturn, I don't seem to see any results on the R plot window (although the window pops up). Is there anything to do with the code of R.dll wrapper

On IBM RS/6000 AIX 4.2, I built R-1.2.1 with % env CC=xlc CXX=xlC F77=f77 FC=f77 ./configure R is now configured for powerpc-ibm-aix4.2.1.0 Source directory: .

I am a user of a i book G4 with OS X 10.3 and I installed RAqua 1.8.1 without any problems. When I want to start RStart the "R" Symbol appers for one second and then disappers again and nothing else happens. I've tried to reinstall the program and I also reinstalled my OS X wich did not help. I really need this program for my studies. If someone knows whats wrong please eMail

Hi there, I am using C++ Builder 5 to develop windows GUI interface for a R library package. I have to pass R objects to and from C functions and also evaluate them within C functions. But I always got linking error message of "unresolved external functions" with those internal functions or macros defined in Rinternals.h file. I can not find the reason. I have included R.h and

Dear R developers, I am building an ActiveX Com wrapper for R. I have successfully implemented an Evaluate function using rproxy_impl.c and rtest.c as examples. The Com object as it stands at the moment is similar to Thomas Baier's automation server StatConnectorSrv.exe except that it does not use the Proxy. My goal it to include a couple of activeX controls in the library: One to provide a

Hello, I just installed RExcel but I have some problems.

I develop quite a bit of R code that I tend to distribute, or let other people embed in their software. One of the things I'd really like to do is find a way to load an R library I've developed, and call one function with arguments. Currently, I achieve that by building a separate R client file, which reads in the command line arguments, loads the library, and calls the main

Hi everyones, I have a production server using asterisk 1.6.0.6 using php as an IVR and mssql server (on other machine) My server attached a Sangoma A104 card (4xT1 card) i have a problem with memory leak on that server and causing a delay on IVR prompt.
