User-defined RNG with the standalone Rmath library
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

Studio 11 compiling of Rmath standalone versus compiling R
Hi,
I have a UNIX-Solaris-Sparc-Studio 11 compilers question. Since it's not exactly a programming question, I'm posting it here instead of to the developers list.
Here's the relevant 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

No Rmath.h when making just standalone library
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 issue were just

defines in Rmath.h and R_NO_REMAP
-----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 have been having trouble using R's standalone random number generators

Rmath.dll importing in VB6 problem
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.

Making rmath.dll (or equivalent)
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.

Rmath library problems
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

Standalone Mathlib, C++ and ISNAN()
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

The following code (using rgamma) hangs
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

I'm using Debian squeeze, and the code was tested with r-mathlib 2.11.1-6

question on suppressing error messages with Rmath library
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 look at the function dnt.) However, to have this happen a

compile error with C code and standalone R math C library
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.

Calling Optim() from C
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

nmath standalone again
Hi !
I have again problem with nmath standalone sources package.
Following the suggestion of Reid, I did control that
/usr/local, in which I copied the dir standalone, is listed in
/etc/ld.so.conf.
However, because of my big ignorance, I don't understand how I have to do
the linkage to Rmath during the compilation of a source.
What does it mean:
"and link against -lRmath" in
