Thanks, everyone for all the help! So, here is my calling function in C
(called

trouble using R Mathlib as standalone
Dear People,
I am trying to use R's Math library as standalone, as documented in

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

Problems when linking to R shared library
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

could not open libRmath.so
Hi
I got a very tricky problem when I tried to compile a C++ program
which links to libRmath.so. The program itself had no problem, I can
compile and run in my own linux machine where I compiled libRmath.so
file and copied it to system directory (/usr/local/lib).
Now I want to compile my program at another linux box where I don't
have root privilege. That machine only has binary version of R,

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
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).

Mathlib
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

library file for R's nmath routines
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!

Catching warning message(stdout) from C
I'm using the 'pnt' C function from Rmath library in some C-code.
How can I catch the warning message: "full precision was not achieved in

(options(warn=-1) didn't work)
Thanks in advance
