Hello. I'm solving ODEs in R. I need "as many methods as possible", so I downloaded the Fortran functions from http://www.netlib.org/ode/. Then I created DLLs and dyn.loaded them to R. Problem is that I don't know how to use them. I've been trying for many days and can't solve it. So I would be very glad if you could give me some link (or whatever) where I can see how to

I'm having a dynamic loading problem that seems to be caused by exponentiation (the ** operator in Fortran/ratfor). This can be illustrated by the following toy example: ===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+===+=== % cat foo.r subroutine foo(x,n) x = x**n return end % f77 -c foo.r /tmp/ratfor.06661.0.f: foo: % R CMD SHLIB -o foo.so foo.o gcc -G -o

Hi All, While attempting to build R-patched using the Portland Group compiler suite on our dual Opteron 250 box running Scyld 29cz5 (based on RH, kernel 2.4.29), I get: make[5]: Leaving directory `/home/andy/Rbuild/R221-pgi/src/library/tools/src' make[5]: Entering directory `/home/andy/Rbuild/R221-pgi/src/library/tools/src' pgcc -I../../../../include -I/include -I/include/CC -fpic

hi R-users, a few days ago R 2.2.1 came out. on my win xp i'installed R 2.2.0. along the time i've installed a lot of contributed packages. my internet-connection is not very fast. so my question: is it possible after installing R 2.2.1 to do copy/paste the contributed packages from the C:\Programme\R221 to the C:\Programme\R2.2.1- location in the files system? or have i to download

Hi, I'm using dyn.load to load a shared library (compiled from C code) into R. If I dyn.unload it and then dyn.load it again, I get an hourglass icon in Rgui (R 1.7.0, Win 2000), and it just sits there forever. I can't press Escape to stop the current computation, but I can close Rgui without resorting to using the Task Manager. Is it a problem with my use of R_alloc? Do I need

dear list, since matrix manipulations is often of interest in statistical computations, i'd like to get a working example of using Lapack for regression. However, i run into an error. My matrix-lapack-example.c file: #include <R_ext/Lapack.h> void reg(const char* trans, const int* m, const int* n, const int* nrhs, double* a, const int* lda, double* b, const int*

Full_Name: Jonathan Tuke Version: 2.4.0 OS: Mac OS X 10.4.8 Submission from: (NULL) (203.173.46.189) I am writing C code to implement in R. I am using R CMD SHLIB and then dyn.load("file.so"). The function I then call with .C("function"). Since I installed the latest R version, I have found that if I alter my C code and recompile, then use dyn.load("file.so"), the

Hello, I have a probleme with the dynamic loading. I make two librairies "myfct.so" and "otherfct.so", where "myfct.so" is calling functions of "otherfct.so", and I want dyn.load() each of it, without generating a unique librarie. For exemple : myfct.c : void myfct(double *x, double *y) { otherfct(x); *y=(*x)+1.0; } myoth.c : void otherfct( double *x

I tried to dynamically load a c++ function. Everything seems to be OK when dyn.load() is executed but then I get this error Error in .C("integral", sumInMean, sumInVar, boundError, numberSampleClasses, : C/Fortran function name not in load table The code of the function is something like this: #include <cmath> extern "C" { #include

Hi R-Users I wrote 1 week ago asking about a message that appears when I try run dyn.load. I'm trying to do an example in C code from "Writing R Extension" to learn how to do it. I have R 2.0.0, Rtools, Perl and MinGW as describe in http://www.murdoch-sutherland.com/Rtools/ with path sets. When I use C:\R\rw2000\bin>RCMD SHLIB -o C:/dev-cpp/teste.dll

Hi, I've just about got myself transferred from windowsXP to Linux (Mepis 3.3.1-1). I've got R 2.1.1, emacs, and ess running from the debian repositories. Of course, there is a hitch. I have a bit of C code in one of my personal functions. I have, apparently without problem, been able to compile it using R CMD SHLIB, but when I try to dyn.load it I get the following error: >

Dear R-list, I want to use shared library of gsl in R(2.15.1) on unix .I have a makefile such as CC = gcc CFLAGS = -fPIC -O2 PKG_LIBS -lgsl -lgslcblas -lm -lpthread ?

I hope that someone reading this list can offer some suggestions on how I can incorporate external C libraries in C functions that I want to call from R. I have gone through all of the documentation, help files and mailing list archives and have not been able to find a satisfactory solution. I have constructed a simple example of the problem, since my "real" program is much more

Hi, I am writing a function in C that is meant to be called by R. In the C function, I used a gsl function gsl_stats_mean. The code is as simple as below void gsl(double *m, int *dim){ int r, c; r = dim[0]; c = dim[1]; double mean = gsl_stats_mean(&m[0], 1, r); Rprintf("mean = %f\n", mean); } The C code is succesfully compiled and the output is as follows. $ R CMD SHLIB

Hi, here are a couple of strange things happening with R.2.2.0 compiled under Mandrake-10.1 At the begining of the story I have segmentation fault using package RandomFields in conjuction with some Fortran code of mine loaded with dyn.load. One of my fortran programs contains a subroutine named fstat Trying to trace , I simplified the sequence as much as possible and I end up with the the

Hi! I would like to call a Fortran subroutine within R. For doing this, I first built a shared library for loading into R under Unix and it was successful. But when I tried to load a shared library using dyn.load() function for use in .Fortran(), I got an error message. The command I input below in R is: >dyn.load("aaa.so") The reslut is: error in

Hi! I am studying C language to run with R 2.0.0. My system (Windows ME /BR) is configured to run RCMD ( I have installed ActivePerl, Rtools and MinGW as indicated in http://www.murdoch-sutherland.com/Rtools/ an with correct path). I would like run the coded write below named conv.c (Example from "Write R Extension") : #include <R.h> #include <Rinternals.h>

Following the recommendation of Prof. Ripley, I have created the Makevars file with the line: PKG_LIBS="-L/usr/lib/libm -lm -L/usr/local/lib/libgsl -lgsl -L/usr/local/lib /libgslcblas -lgslcblas" in the working directory. Now I have the code file Example3.c which computes the Bessel function value (the example is taken from the GSL reference book). I am running: R CMD SHLIB Example3.c

Hello R experts I am googling and reading around, however, I can't get it working (perhaps because I do not understand much C, however, I'll give it a try). I am trying to include C++ code into an R routine, where the C++ code looks: #include <iostream> using namespace std; void foo (double* x, double* y, double* out) { out[0] = x[0] + y[0]; } Back in R, the command R CMD
