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

Dear R-devel, The latest version of R-devel (05-17) is throwing an error for me when building on OS X (v 10.11.4): making Rembedded.d from Rembedded.c making dynload.d from dynload.c making system.d from system.c making sys-unix.d from sys-unix.c making sys-std.d from sys-std.c making X11.d from X11.c clang -I. -I../../src/include -I../../src/include -I/usr/local/include -DHAVE_CONFIG_H

I had actually tested them and things seemed to work, but it was on a different machine and not a completely clean build. Indeed a problem. I'm pretty sure that RL_UNSETSTATE()

Hi, I'm just learning to write R extensions in C and to embed R in C. I was trying to get through the example in the help page on calling the .dll directly ( http://cran.r-project.org/doc/manuals/R-exts.html#Calling-R_002edll-directly ). When I compile I consistently get the error that getDLLVersion() as well as get_R_HOME() and getRUser() are undefined references. These are defined in

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

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

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

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"

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

Hi, I think this is a bug (even though I can't find documentation explicitly saying that it should work). Basically, Rf_PrintValue(obj) fails when 'obj' is an S4 object that should be printed using show() rather than print(). From the error message I'm guessing that the need to use show is detected correctly but then show is not found. "cbind2" in the code below is just

Hi I think I have asked these questions earlier, but I been able to find answers from the documentation (which I found poorly written in several places). Will someone be kind enough to give me answers and enlighten me? (as in explain with CODE?) I want to embed R in my application and use the fPortfolio package for carrying out risk management computations. Right now I'm reading the Rmetrics

While doing some embedded programming and trying to figure out how to generate a hand coded SEXP equivalent of the line "t.test(x,conf.level=(1-p))$conf.int[2]" I had an idea for an addition to the embedded API. There are a number of hidden or static parse functions (R_ParseBuffer, R_Parse1Buffer, etc.) which take an IoBuffer* and returns a parsed tree. If one or more of these

Hello, The package builds successfully on RHEL5 and OS X( 64 bit,32/64 respectively) but on FC4(32 bit) it fails with this error g++ -m32 -I/usr/include/R -I/usr/local/include -fpic -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables -I. -g `pkg-config --cflags protobuf` -Wall -c

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

Hi, I've been trying to get a shared library version of the R package(version 2.12.1) installed on a CentOS 5 system. (It installs fine without but other packages demand shared libs - namely Rapache). I've tried this with yum but don't know of any flags to set to tell it to installl with shared libs enabled. I then tried a local R install as non-root with source packages: after

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

Hi. (MacOSX 10.4.6) I downloaded R-latest.tar.gz just now from src/base- prerelease on CRAN.

Hi I'm trying to implement something similar to the following R snippet using C. I seem to have hit the wall on accessing class slots using C. library(fPortfolio) lppData <- 100 * LPP2005.RET[, 1:6] ewSpec <- portfolioSpec() nAssets <- ncol(lppData) setWeights(ewSpec) <- rep(1/nAssets, times = nAssets) ewPortfolio <- feasiblePortfolio( data = lppData, spec = ewSpec,
