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...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I'm programming with R 2.7.2 and had some trouble including Rmath.h for its random variates generation routines: Although I define R_NO_REMAP (which works fine for Rinternals.h stuff), Rmath.h defines "beta" as "Rf_beta" etc., so that my "beta" strings get redefined as well! Is this a feature? I found an old Rmath.h version from 200...

...nk 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. Anyway, i reviewed pnorm.c file which was in the directory tree of project R i downloaded, and it has two functions in it: pnorm5 and pnorm_both i have successfully imported the Rmath.dll file into my VB6 program, the matter is that now i am...

...the Ubuntu host for the Tesla, I was trying to install the cudaBayesreg package. This gets its compile-time include path by doing an `R RHOME` and adding "/include" to it. It thus ends up trying to compile a source code file using -I/usr/lib64/R/include but that fails to pull in the Rmath.h include file that the source file requires but doesn't find, not least because there is no `R RHOME`/include. I thus went looking for said Rmath.h and found one to be at: /usr/share/R/include/Rmath.h and so tried to get the cudaBayesreg installer to take notice of that location. I tried...

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 on my co...

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 random...

...send this question, but I have a question about cross-compiling R. I am working with R-1.9.1.tgz. It may just be with my version of mingw32, but it seems that expm1 is not defined, so I tried to ensure that HAVE_EXPM1 was #undef'ed before cross-compiling. The problem is that, in <include/Rmath.h> if it is #undef'ed it is then #define'd as 1, meaning that the line where expm1 is declared automatically not included. I had similar problems with logpq, but after changing Rmath.h cross-compiling was straightforward. My question is: is this a "bug" in Rmath.h with resp...

...t info: 1) I'm using SunOS 5.9 on a 32 bit machine without parallel processing. The chip is Sparc. 2) I've installed the Sun Studio 11 compilers. 3) I've successfully built and tested R 2.5.1 with Studio 11--all the make checks were successful as were my own tests. 4) The README to the Rmath standalone library warns that mlutils.c _cannot_ be compiled with Sun's cc compiler because it can't do compile-time floating point arithmetic. This is confirmed by the output I get when I run the make (after the full R package was built and installed): (cd ../../include; make Rmath.h) `Rm...

When making only the standalone math library, include/Rmath.h is not there, so compilation fails. A solution is to go to src/include/ and just say `make Rmath.h' there first. This is with R-2.2.0 on GNU/Linux on i686. The failing steps are: tar xzf ../R-2.2.0.tar.gz ./configure cd src/nmath/standalone make Would be nice if this worked, or if the issu...

Dear list, I have been using the Rmath library for quite a while: in the current instance, I am calling dnt (non-central t density function) repeatedly for several million. When the argument is small, I get the warning message: full precision was not achieved in 'pnt' which is nothing unexpected. (The density calls pnt, if you...

Dear R-experts, I have been having trouble using R's standalone random number generators from C on my Mac OS X 10.4.8 system. I try to compile my C program in the following way: gcc -Wall -o helloMac helloMac.c -lm -lRmath I get the following error: /usr/bin/ld: can't locate file for: -lRmath I am unable to locate Rmath on my machine. The problem appears to be that no libRmath.a was built on my Mac OS X installation. Any pointers (perhaps to a step by step guide for a _beginner_ on how to install this and th...

Hi, I am a c/c++ programmer attempting to utilise the Rmath library (looks VERY useful). I have downloaded the Rsource and compiled the library as recommened (compiled on windows 98 using the cygwin environment). But whenever i try to use functions from the library i get similar error messages - eg. using the function dnorm(double, double...... etc ) i...

Hello, I can't link a c code with Mathlib according to introduction of R manual "Writing R Extensions", page 60. It is written : "It is possible to build Mathlib, the R set of mathematical functions documented in 'Rmath.h?, as a standalone library 'libRmath? under Unix and Windows. (This includes the functions documented in Section 5.7 [Numerical analysis subroutines], page 61 as fromthat header file.) The library is not built automatically when R is installed, but can be built in the directory 'src/nm...

Hi, I want to use R_qsort_int_I() in my C function, but getting the following error.

Dear all, I have been trying to build standalone Rmath library for irix 6.5, but, could not get it due to some reasons, if anyone would like to share already built ones, please let me know, I appreciate all of your help. Sincerely; Scott

It appears the Makefile.win in src/nmath/standalone might need some modification since cd src/nmath/gnuwin32 make -f Makefile.win make -f Makefile.win test fails. However if I remove libRmath.a from line 15 OR modify lines 67/68 replacing Rmath.a with libRmath.a then make -f Makefile.win test goes as expected. _________________________________________________________________ -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list --...

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 test(int *nrows, SEXP init,SEXP fac1, SEXP typeordi, SEXP bgratio) { double sum = dnorm(1.0/1, 0, 1, 0); } Compiling and building shared library: g...
