Using R.dll in .NET IPC
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

R.DLL mapping by P/Invoke
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

R_ParseVector problem: it's cutting off after the decimal point
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

Problem with initializiing R main loop under Windows (R.dll-version: 2.15.1)
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

Controlling stdin and stdout in an embedded R instance
Hello, I am very new to R but my question is with respect to the C API for working with an embedded R console. I have been able to start and stop an embedded R console from within a C program as well as use the API to execute commands in it. I am seeking a mechanism to individually send native R commands to an embedded console and then consume the output of these commands. Specifically, I

Windows environmental variables
Hi, I recently had some difficulty getting an embedded R session running on Windows, due to the way that R Sys.getenv works, which I would consider a bug. Even if you do not agree, then you may still want to document it for future users who might be bitten. As outlined in R-exts (?8.2.2): http://cran.r-project.org/doc/manuals/r-release/R-exts.html#Calling-R_002edll-directly R_HOME/bin needs to

Latest R-devel build failing on OS X
Yes, the nightly build is broken in a similar, but different way. See below. Both seem to be readline related, so Frederick Eaton's patches, which Martin committed yesterday are the likely culprit. I had actually tested them and things seemed to work, but it was on a different machine and not a completely clean build. -pd ..... ranlib: file: libR.a(printf.o) has no symbols gcc

License for Rembedded.h
Possibly more of a legal question than a technical development question, but here goes. In the doc\COPYRIGHTS file it is made clear that the intention is that you can write R packages and distribute them under licenses not compatible with GPL, by making the relevant header files available under the LGPL. This was an explicit change that was made in February 2001, and allows for DLLs that

The best way to use R's linear algebra functions from C
First of all, thanks to everybody for R. I have written a program in C that requires some basic matrix operations, namely the following: - matrix multiplication and addition, - determinant and transpose, - inverse of a symmetric matrix. Since I am a happy R user I thought I could call R from within my program for this purpose. I read "Writing R Extensions" and "R Internals"

Rf_initEmbeddedR in Windows
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

Is R GPL or LGPL (or can I write a commercial front end to R)?
Note I'm not asking for any legal advice here obviously, simply what the intention of the R foundation is with regard to allowing commercial connection to R. I've looked at various threads on the r-devel archive and it looks like this may have been discussed before, but as far as could tell, not to any great resolution, and not, it seems, specifically covering this angle. In the

Child thread libR.so
I did some poking around with GDB and confirmed that the advice of setting R_CStackLimit after init, which is echoed in the "threading issues" section of the R-exts help document, isn't entirely useful because init apparently loads the main package which trips over the broken stack checking. Stack trace: #0 R_SignalCStackOverflow (usage=140732197147604) at errors.c:81 #1

R in standalone application
I am trying to build a C application where I need to compute some statistics to take decisions about the direction to give to a user, knowing his/her habits. Because I used R back at school, I thought I can use some of his functions in my application, as a shared library. I reviewed the "Rinternals" and "R extensions" documents, and decided to give a try to the

I want to get a reference to this time series object
I'm trying to get a reference to this object in C SWX.RET[1:6,c("SBI,"SPI","SII")] While i am able to access and use a plain SWX.RET object, I'm getting confused on how to create an object with the array subscripts like above. Here is what I tried to do. It doesn't work because "[" is obviously not an operation or function on SWX.RET. So how do I

bug in Rf_PrintValue ?
I'm very green with R, so maybe this is not a bug, but it looks like one to me. The following program segfaults at the second call to Rf_PrintValue(). To failure depends on the value of the y-string. E.g., if I change it from "coverage" to, say, "COVERAGE", the segfault does not occur. /* bug.c */ #include <stdio.h> #include <Rinternals.h> #include
