xerbla called from BLAS routine (PR#8100)
Full_Name: G?ran Brostr?m
Version: R-2.1.1, 2.2.0
OS: Debian unstable
Submission from: (NULL) (213.65.9.59)
Some BLAS routines call xerbla for error messages, which results in a message
like
"LAPACK routine DGER gave error code -9".
Suggested solution: In
void F77_NAME(xerbla)(char *srname, int *info)
{
/* srname is not null-terminated. It should be 6 characters. */

Fortran subroutines dblepr, realpr, intpr
I am making my first attempts at using some Fortran code with R, and
so far it's going OK. To print from my Fortran programs, it seems I
need subroutines dblepr, realpr and intpr. From the excellent
"Writing R Extensions" document:
"Three subroutines are provided to ease the output of information
from FORTRAN code.

How to call DBLEPR in Fortran code to be used by R
Hi
I've built a dll using Fortran code and can call it by either R or
Fortran. Calling by the former gives me the wrong answer and the later
gives the correct answer. From what I've read, it looks like I should use
the subroutines DBLEPR, INTPR and REALPR to get values to show up in R
which I hope will allow me to find the error. I've downloaded the
R-2.12.0.tar.gz but have

Fortran character strings
Has anyone ever successfully used Fortran character strings with R?
?Foreign says
R C Fortran

character char ** [compiler dependent]
Character strings are passed as C arrays of character
strings to Fortran: the first string may be usable if
its length is passed

R problems with lapack with gfortran
Hi,
I have tried to pinpoint potential problems which could lead to the
LAPACK issues that are currently seen in R. I built the current R
trunk using
AR=gcc-ar RANLIB=gcc-ranlib ./configure --prefix=$HOME --enable-lto
--enable-BLAS-shlib=no --without-recommended-packages
and used this to find problem areas.
There are quite a few warnings that were flagged, due to mismatches
in function

registering Fortran routines in R packages
Dear list,
I?m trying to register Fortran routines in randtoolbox (in srt/init.c file), see https://r-forge.r-project.org/scm/viewvc.php/pkg/randtoolbox/src/init.c?view=markup&root=rmetrics.
Reading https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Registering-native-routines and looking at what is done in stats package, I first thought that the following code will do the job:

(not) compiling fortran -- dynamic loading problem
Hi, everyone. This may be properly a fortran question rather than an R
question.
I'm trying to add a few print statements to otherwise working fortran code
in one of the libraries so I can see what's going on in the code. I have
no problem doing so on an SGI machine, but under LinuxPPC I've run into a
problem. The code compiles and creates a shared object (.so), but when I

precision when calling a C function; presence of Fortran call
I'm trying to figure out why the presence of a Fortran call affects the

c0 = (double) *n * *f;
outC = floor(c0);

Calling FORTRAN function from R issue?
Hello,
I am trying to call the BLAS Level1 function zdotc from R via
a .C call like this:

passing char's from C to Fortran (mac os x)
Hello All,
In some package I use a c-routine which calls a fortran routine which
expects a char-string as input.
As per the writing R-extensions manual,
the Fortran routine is declared in C as:
void F77_NAME (setoptions) (char **option);
and then it is calles as follows:
char **option;
option = new char*[1];
option[0] = new char[256];
option[0] = strcpy(option[0],"Iteration

Error in simulation. NAN
Hi all,
im triyng to implement a bayesian model with R and c++.
I have a strange problem. I can't reproduce the error with a small
script and then i post the original one.
The problem is after the line

For the first 34 iterations all work fine, after, all the simulations
of mu_acc_P return an "nan". If i delete the line

Replace isnan and lgamma in Fortran subroutine in R package
Hello,
I submitted a package which used Fortran functions isnan and lgamma. However, I was told that:
isnan and lgamma are not Fortran 95 functions.
I was asked to write 'cross-platform portable code' and so should not be writing GNU extensions to Fortran.
See http://cran.r-project.org/web/checks/check_results_mpath.html, which will shortly show installation failures under Solaris.

F77_CALL, F77_NAME definition
I give up. Maybe it is my search (Windows) but I cannot seem to find the definition of the F77_CALL or F77_NAME macros. Either there are too many matches or the search just doesn't find it. For example where is the source for:

?
Thank you.

reusing external functions across libs
Hi,
I am searching for a way to solve the following problem:
I want to use an external function, defined in a dyn.load()ed shared
object, in another dyn.load()ed shared object.
Currently I have to take the sources (Fortran) from one libraries src/
directory and copy them into the src/ dir of the other library, resulting
in two copies of this function. This is bad for maintanance and maybe

Simple reason: I was not able to compile it successfully under Windows.

Lapack / dgesvx function declaration

I'm writing some c-code to solve a numerically tough problem for me in
