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() {...

First of all I would like to join the chorus of approval over the release of R 1.0.0. It really is an excellent piece of software. I'm sure you will astonish us again with Omega. I have a query about Mathlib. It is such a nice collection of functions that it would be nice to use it in other software, not necessarily related to R. Is it possible to build Mathlib separately, and/or install the shared object and the header file in a more public place? Martyn -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-....

Hi, I'm trying to use pgamma() within my C application but I'm getting strange results. I have a Debian system with r-mathlib 1.4.1-1 and gcc 2:2.95.4-9. Here are 3 example pgamma() calls executed by R: $ R -q --vanilla < gamma.R > pgamma(98, 100, 1) [1] 0.4333105 > pgamma(21, 100, 5) [1] 0.7002453 > pgamma(2, 100, 69) [1] 0.9997046 > and here is what the small C program below produces with the same...

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 relevant. The class Cube is defined in lattice.hh and I don't think mh.hh are used at all. I get the following errors when trying to compile this...

In the hope of some meaningful response and ignoring the risk of further abuse, let me try to clarify the issue here. I have re-read the 'Writing R Extensions' manual. It seems to me that it clearly says R API functions can be called from from C++ programs, and the API includes the special values ISNAN() and R_FINITE() and the missing test ISNA(). R_FINITE is no problem. It is

hello all, At my workplace, our colleague Mukesh has just completed a port of speex 1.2.1 to Palm OS. He had to write a couple of mathlib functions, but the trunk remains unchanged. It works quite well, I was wondering if there will be any interest in this port in the distribution. - farhan

I have pulled Jim Lindsey's repeated library and put it under the libraries directory, as are all the other toolboxes. 2 questions: Running R COMPILE *.c and *.f goes fine except that Mathlib.h cannot be found - it is not in the include library. I cannot find any other Mathlib.h on my system anywhere - presumably this is an R specific module. Was this missing from the 0.62.4 distribution - I am using the one that came with the RedHat power tools. \John PS Many thanks to Tom for the...

Thank you for letting us know! {BTW: There's been an ambitious project of binding all of mathlib *and more out of R* to a java script library; But I think that project has taken the typical course of the majority of github projects: "code rut"} > Any chance you could rename it to a more neutral r_mathlib or something? > As a free-standing C library it has lon...

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 do...

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 library hangs. Note that s...

Dear R experts, Could anyone give some concrete examples of how to call R functions from a program written in C++? Thanks in advance for your help.

...x with R 1.9.0. When compiling R with the mingw tools I get an error about expm1 being undeclared when first found at src/main/arithmetic.c:1019 If I fiddle a bit with it later on I also get errors about log1p bein undeclared. Any idea what should I look for? I am using R 1.9.0 in Debian, with R-mathlib avaliable, and gcc 3.3. Thanks, iago

Hello @R-devel I needed some statistical functions for a project I was working on in Rust, and I've used the R math library as a standalone solution. I thought the R developers would be interested in the fact that their work is being used elsewhere, and I also wanted to say thanks for some code I do NOT want to have to write myself! The "crate" (Rust's name for a package) is at

Hi all, The systems guys here in the stat dept don't seem to be able to compile R on the Dec Alphas or on the SGIs.

I need some random numbers in my C program. Here a small example: //////////////////////////////////////////////////////////////////////////////// #include <R.h> void rand (int* n) { int len = *n; for (int i = 0; i < len; i++) Rprintf("%1.5f ", unif_rand()); } dyn.load("rand.dll") .C("rand", as.integer(10)) dyn.unload("rand.dll")
