similar to: building a Win32 DLL with R objects?

Dear List, I stepped into a strange effect which I can't explain to myself (probably due to lack of knowledge on R internals). I have four vectors a,b,c and z of size 10000 each. With these vectors I call .Call("hyp2f1forrey", a, b, b, z, PACKAGE = "hyp2f1") to access SEXP hyp2f1forrey(SEXP a, SEXP b, SEXP c, SEXP x) { int i,n; double *xa, *xb, *xc, *xx,

Hi when I call the function below in R, i get the error: Object 'pairlist' can't be converted to 'double'. #include <R.h> #include <Rdefines.h> #include <Rmath.h> SEXP CSimPoisson(SEXP lambda, SEXP tgrid, SEXP T2M, SEXP Ni, SEXP NT) { double sign, EVar; double *xlambda, *xtgrid, *xT2M, *xNi, *xNT, *xtau; SEXP tau; int ltgrid =0; int i = 0; int j = 0;

Hello: This is a simple, I hope, question about the first example in section 3.6.4 of the manual, "Writing R extensions." I'm using R 1.1.0, and below I list some easy code that I got from section 3.6.4. When I try to compile the file out.c under NT 4, using VC++ 6.0, I get the following error messages: Compiling... out.c Linking... out.obj : error LNK2001: unresolved external

I'm continuing my work on finding speedups in generalized inverse calculations in some simulations. It leads me back to .C and .Call, and some questions I've never been able to answer for myself. It may be I can push some calculations to LAPACK in or C BLAS, that's why I realized again I don't understand the call by reference or value semantics of .Call Why aren't users of

Hi, I'm a highschool student, I'm looking for information about converting Wave file (*.wav) into Ogg file (*.ogg) and i found encoder_example.c inside libvorbis's example directory. I try to compile it using Microsoft Visual C++ 6.0 ,but it goes error like this : --------------------Configuration: encoder_example - Win32 Debug-------------------- Linking... encoder_example.obj :

Hello, Apologies if this has been done before. I just joined the list as this has bugged me for a while. I can compile FLAC 1.1.2 using Visual C++ 6.0 with no problems. However, when I try to compile the CVS source I get: Linking... utils.obj : error LNK2001: unresolved external symbol _snprintf grabbag_static.lib(stream_decoder.obj) : error LNK2001: unresolved external symbol

Hello everyone. Due to problems with libsndfile's handling of FLAC files, Mixxx is going to use libFLAC directly in v1.9.0. I'm the Windows packager and am trying to build libFLAC on Windows x64 using MSVC 2008 and the following steps that I've put together: http://mixxx.org/wiki/doku.php/build_windows_dependencies#libflac The problems I have are the following: If I try to build the

Hi guys, I discovered xapian today and I'm trying it because it looks promising compared to other FTS engines. However I'm in a windows environment so it's a bit painful to set up as there is no official binaries. I've heard about http://www.flax.co.uk/xapian_binaries And I'm trying to build their latest release (1.2.8). After a few tries I manage to compile everything with

Dear R-developers, Using .Call I pass a S4 class with e.g. the following class definition: setClass("mmatrix",representation( data="matrix") ) On the "C side" i do mat = GET_SLOT(vs,install("data")); and then: printf("%f\n",NUMERIC_POINTER(mat)[1]); The above print statement produces the correct output if xx<- new("mmatrix")

I've searched to find examples of how to work with the C versions of optim. I've separated out the function just to test on it alone, and currently I'm attempting to use fmmin as follows: !~~CODE ~~! double optimfn(int n, double *par, void *ex) { double * lambda = (double*)malloc(sizeof(double)*n); double sum = 0; for(int i =0; i < n; i++) { lambda[i] =

I would like to utilise the power of R by adding my own software as a package written in C++. As a first step I am trying to write a DLL with a simple function that can be called from R. The DLL contains a C++ routine written and complied in Microsoft Visual C++ Ver 6.0 and is based upon the example in R-Exts eg I am trying to create the following example function SEXP out(SEXP x, SEXP y) {

Hi, I've started making an Ogg Vorbis SDK, as per IRC topic instructions :) Some questions: Its just targetting MSVC right? Not borland/whatever? Should it install the headers/libraries in the msvc dir (c:\Program Files\Microsoft Visual Studio\VC98\(Include|Lib)), or should it put them in the same directory as the document (c:\Program Files\Ogg Vorbis SDK\(Include|Lib)), and have the sample
