similar to: Call user written R functions in C

Hi R Users, Thanks in advance. I am using R-2.5.1 on Windows XP. I am trying to call C code (testCX1.C) from R. testCX1.c calls another C code (funcC1.c) and returning a value to testCX1.c. I like to have this value in R. My steps are below: 1. R CMD SHLIB testCX1.c funcC1.c (at command propmt) 2. It creates testCX1.dll with warning (but testCX1.dll works):

I have two questions about using a user-defined random number generator (RNG) with the standalone Rmath library. The default RNG with the standalone Rmath library is the Marsaglia-multicarry generator, which has poor properties. The "R Installation and Administration" manual, in the section "The standalone Rmath library", states that: ``` A little care is needed to use the

Hi, I've been trying to get this working for ages, but it causes R to hang. Here is my C code saved as test1.c # include <R.h> # include <Rmath.h> void test1 (double *x, double *result) { result[0] = rgamma(*x, 2.0); } This was compiled using R CMD SHLIB test1.c & loaded in R using: dyn.load("test1.dll") out <-

Hi, I am facing a problem which i think i need to explain it to you with some background. I need to use the Project R pnorm function in Visual Basic 6.0. I have already installed R and this is how i perform and get back the result: > pnorm(2, 15) [1] 6.117164e-39 which is what i need. I have already installed R, i generated the Rmath.DLL file out so i can import it into my VB6 and use it.

Hi everyone, I meet the problem to call R from C. Can someone tell me is it possible to call time series functions(such as ar and arima)from C program on linux platform, and then compile the C program to a standalone executable file? I know we can call some function defined in Rmath.h , but I have not found the entry point for time series function. I would very much appreciate

I currently have R 2.12.1 installed, both 32 and 64 bit. I also have a file that was passed to me named rmath.dll. I do not know what version of R it was created from, but I do know it is 32-bit only. I am developing an application in C# that uses this library as a reference but I have to downgrade it to 32-bit in order to use the DLL file. I wish to make a rmath.dll from the version of R I have

Dear R users, I read on the "Introduction to the .C Interface to R" by Peng & Leeuw (http://www.biostat.jhsph.edu/~rpeng/docs/interface.pdf) that it is possible to use a few R functions (such as "dnorm") within C by including the "Rmath.h" header file in your C code: e.g. #include <R.h> #include <Rmath.h> void kernel_smooth(double *x, int *n,

Dear Listers, I am trying to use "rbinom" in my C code, but i always get zeros as output no matter the probability. Am not sure what I am doing wrong because the function has worked before. Attached in an example. Noticed that "rbinom" expects 'n' to be REAL. Regards, Vumani R 2.3.1 (2006-06-01) Windows XP Gcc /* Called this file binom.c and then ran rcmd shlib on it

Dear R users, I would like to use several R functions from a C-code and I have read the "Introduction to the .C Interface to R". Unfortunately, my shared library with the C-code works only in cases where I use R-routines that are defined Rmath.h, eg. ************************************* less test.c: #include <R.h> #include <Rinternals.h> #include <Rmath.h> void

Hello, Has anybody successfully called the Rmath library from C using the MS Visual Studio compiler (I am using Visual Studio 6.0)? I have compiled the Rmath library using gcc, and the 'test.c' program (which makes a call to qnorm) works fine when compiled with gcc. However, I get a fatal memory error when I run it after compiling it with Visual C. Would this memory problem be related

Greetings, I am trying to call simple C-code from R. I am on Windows XP with RTools installed. The C-function is #include <R.h> #include <Rinternals.h> #include <Rmath.h> #include <Rdefines.h> // prevent name mangling extern "C" { SEXP __cdecl test(SEXP s){ SEXP result; PROTECT(result = NEW_NUMERIC(1)); double* ptr=NUMERIC_POINTER(result); double t =

Hello, I would like to call nlm from my MS VC++ application via R.dll. I see that Rmath.h provides interfaces to some functions, but not all. I also see that I can build a "front-end" to R and then parse the results. But I'm unable to find any simple way to just link in R.dll and call the function directly from my application. Is this possible? Thank you,

Dear all, I have a problem in calling my C code from R. If I do not need to use #include<R.h>, the codes work properly. But when I need to use it, my codes produce an error as: logpostCLM.cpp:7:15: error: R.h: No such file or directory logpostCLM.cpp:8:24: error: Rinternals.h: No such file or directory logpostCLM.cpp:9:19: error: Rmath.h: No such file or directory logpostCLM.cpp:10:24:

Hi All, I am new to this area and use Rcpp to call C++ from R and try to build the package under Windows 7. I use Rtools and R 2.10.1 32bit. Everything works fine with me, except using R functions like "rnorm" or "runif" in the C++ code. When I use "R CMD check" the package, it always return error ** libs making DLL ... g++

Well, For this particular use case why not just transform the parameters at the R level and then call the existing function? Is there not a closed form mapping? ~G On Jul 1, 2016 2:50 PM, "Joshua Ulrich" <josh.m.ulrich at gmail.com> wrote: > On Fri, Jul 1, 2016 at 6:13 AM, Luis Usier > <luis.henrique.usier at gmail.com> wrote: > > Gabriel, > > > >

Hello: I am sure this question was dealt with several years ago. Is the function vmmin() available from Rmath Standalone? If not is it possible to call optim() or nlm() from Rmath in C. Thank you. Mervyn
