Hi, Thanks, everyone for all the help! So, here is my calling function in C (called test.c): #include<stdio.h> #include<stdlib.h> #include<Rmath.h> int main(void) { printf("%f \n",pchisq(2.,7., 1, 0)); printf("%f \n",pnchisq(2.,7.,0., 1, 0)); return EXIT_SUCCESS; } I compile using: gcc test.c -I/usr/lib/R/include

Hi, I'm seeing something that may be a bug in R's standalone math library, which is packaged by Debian as r-mathlib. I reported it to the Debian BTS as http://bugs.debian.org/657573 I'm using Debian squeeze, and the code was tested with r-mathlib 2.11.1-6 (default on stable) and 2.14.1-1 (from testing/unstable). I summarize this report below. The following code with the R math

Hello, I forgot to tell you that I am using Linux OS. And I can?t find directory "src/nmath/standalone". I will send you the test code I am using and the whole operation process.

Hello, dear R experts! I run R on Debian 'sarge' platform. There is 'r-mathlib' package in Debian distribution, which is described as: $ dpkg --status r-mathlib ... This packages provides the libRmath shared and static libraries which can be called from standalone C or C++ code. Well, I use runif() function in test_runif.c: #include <Rmath.h> main() { // ...

Dear People, I am trying to use R's Math library as standalone, as documented in /src/nmath/standalone. I am using C++ in Debian testing, and the versions are as follows: ii g++-3.0 3.0.3-1 The GNU C++ compiler. ii r-mathlib 1.4.0-1 `GNU S' - Standalone R math library I have a file (rand.cc) as follows. I don't think that lattice.hh or mh.hh are very

Folks, I'm fairly sure that I'm doing something stupid, but I'm getting a few really strange results from *some* of the distributions, but by no means all, when I link directly to the R shared library. I've tried this on both Windows with the precompiled Mingw binary of R-2.5.0 (compiling my code with MinGW-3.4.2), and by building R-2.5.0 on Mandriva Linux with gcc-3.4.4 and

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

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

Hello, all, I have the same question as the last mail I sent. I have installed libRmath in my system. But I still can not link Rmath through -lRmath. The whole process is as follow.Is there anybody who is so kind to help me find out the problem? I will appreciate very much.

Dear People, I just went back to an old piece of C code. On trying to compile it with the R math standalone C library I got the following error. Can anyone enlighten me what I am doing wrong, if anything? C file (rr-sa.c) follows. I'm on Debian sarge. I'm running R version 1.8.1. Gcc is version 3.3.1. Thanks in advance. Faheem.

As you may recall, a Debian user complained last year about how R is out of line with respect to the filesystem standards (where, in essence, architecture independent files should be in /usr/share, not /usr/lib). While I more or less just told him to get lost, I think it was mostly BDR who actually added support for this over the summer -- so a public Thanks! first. As of a few weeks ago, I now

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

Hi, I want to use R_qsort_int_I() in my C function, but getting the following error. It looks like there is a conflict between Rmath.h, which I use to generate random numbers, and R_ext/Boolean.h I would appreciate any help to fix this problem. gcc -ansi -g -o Gibbs gibbs.c subroutines.o rand.o vector.o -lm -lRmath -llapack -lblas -lfrtbegin -lg2c -lm -shared-libgcc In file included from

Hi: I followed the README in src/nmath/standalone/ to make the use the command "make shared" to make the libRmath.so file.

Hi, I am wondering where the library file for R's nmath routines are? Doing a search on libR gave me the following: /usr/lib/libRKC16.so.1.2.0 /usr/lib/libRKC.so.1.2.0 /usr/lib/R/lib/libRlapack.so /usr/lib/R/lib/libR.so /usr/lib/libRKC.so.1 /usr/lib/libRKC16.so.1 None of these have the functions in nmath. Any help? Many thanks and best wishes! GT

hello all, I use the R standalone math library in my own C program, and the default R random number generator can be seeded with set_seed(const unsigned int, const unsigned int). How could I seed the RNG with an instance of .Random.seed ? I would need this or a similar workaround for debugging purposes. More precisely, I use the default R random number generator to sample from various

Hi List; I am trying to use wiki via the link (http://www.voip-info.org/wiki/index.php?page=Asterisk) in effective way to find the needed resource for me, but still it is hard to arrive for the needed information. For example: what is the best (shortest) way to search for information related to the command playbak()? Using the backlines, it make the eyes feel hard by keep reading without

Dear People, I have been writing a simulation routine that is currently entirely written in c++. I've been using the R standalone math library to give me random number generation for this. However, I have had to set the seed myself, and I am using set_seed(time(NULL), clock) for every call to unif_rand(). However, this works really badly. The random numbers aren't uniform at all. Does
