unstable corner of parameter space for qbeta?
I've discovered an infelicity (I guess) in qbeta(): it's not a bug,
since there's a clear warning about lack of convergence of the numerical
algorithm ("full precision may not have been achieved"). I can work
around this, but I'm curious why it happens and whether there's a better
workaround -- it doesn't seem to be in a particularly extreme corner of
parameter

question about /nmath/standalone
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

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.

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

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:

trouble using R Mathlib as standalone
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 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

unstable corner of parameter space for qbeta?
Given that a number of us are housebound, it might be a good time to try to
improve the approximation. It's not an area where I have much expertise, but in
looking at the qbeta.c code I see a lot of root-finding, where I do have some
background. However, I'm very reluctant to work alone on this, and will ask
interested others to email off-list. If there are others, I'll report back.

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

qbeta function in R
HI All:
Does anyone know the code behind the qbeta function in R?
I am using it to calculate exact confidence intervals and I am getting
'NaN' at places I shouldnt be. Heres the simple code I am using:

> x<-NULL
> p<-rbeta(k,3,3)# so that the mean nausea rate is alpha/(alpha+beta)
> min<-10
> max<-60
> n<-as.integer(runif(3,min,max))

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!

error in qbeta (PR#1201)
Full_Name: Ziheng Yang
Version: 1.3.1
OS: Windows 98
Submission from: (NULL) (172.136.54.89)
I noticed that qbeta is sometimes wrong and the error is not even due to the
beta parameters being too extreme. I am calculating the quantiles corresponding
to cdf = 0.05, 0.15, ..., 0.95. The value corresponding to cdf=0.25 is wrong
while all other values are correct.

less precision, please!
I need to run qbeta on a set of 500K different parameter pairs (with a fixed quantile). For most pairs qbeta finds the solution very quickly but for a substantial minority of the cases qbeta is very slow. This occurs when the solution is very close to zero. qbeta is getting answers to a precision of about 16 decimal places. I don't need that accuracy. Is there any way to set the precision of

qbeta function (FYI, compiler bug)
Hi there,
this is just to let you know that the qbeta function, which was
copied from R into Gnumeric, has been confirmed to be miscompiled
by gcc 2.96 on Linux. (That's Red Hat's compiler.)
This shows by qbeta(0.025,4,0.5) ending up taking the wrong
branch of "if (alpha <= 0.5)".
We compile things in a different context, so this may or may not
affect you. The qbeta

Code density functions
Hello
I would like to see the algorithm that R uses to generate density functions
for several distributions (i.e. Normal,Weibull, etc). I tried:
>dnorm
function (x, mean = 0, sd = 1, log = FALSE)
.Internal(dnorm(x, mean, sd, log))
<environment: namespace:stats>
How can I see the code used for densities?
Thanks!

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).
I summarize this report below. The following code with the R math
