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

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
mentioned in

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

What should dnorm(0, 0, -Inf) return?
Yes, that looks like a bug and an easily fixable one too.
However, I spy another issue: Why do we check the !R_FINITE(x) && mu == x before checking for sd < 0 ? The difference is whether we
return ML_NAN;
or
ML_ERR_return_NAN;
but surely negative sd should always be an error?
I'd be inclined to do
if (sigma < 0) ML_ERR_return_NAN;
if(!R_FINITE(sigma)) return R_D__0;

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?

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.
I wish to make a rmath.dll from the version of R I have

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

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)

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.

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

What should dnorm(0, 0, -Inf) return?
Hi,
Apropos of a recent Inf question, I've previously wondered if dnorm "does the right thing" with
dnorm(0, 0, -Inf)
which gives zero. Should that be zero or NaN (or NA)?
The help says "'sd < 0' is an error and returns 'NaN'" and since -Inf < 0 is TRUE, then... is this a bug?
Thank you,

makefile for standalone lib
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.

[PATCH] xl: extend autoballoon xl.conf option with an "auto" option
From: David Vrabel <david.vrabel@citrix.com>
autoballoon=1 is not recommened if dom0_mem was used to reduce the
amount of dom0 memory. Instead of requiring users to change xl.conf
if they do this, extend the autoballoon option with a new choice:
"auto".
With autoballoon="auto", autoballooning will be disabled if dom0_mem
was used on the Xen command line.
