registering Fortran routines in R packages
...FortEntries[] = {
{"halton", (DL_FUNC) &F77_SUB(HALTON), 7},
{"sobol", (DL_FUNC) &F77_SUB(SOBOL), 11},
{NULL, NULL, 0}
};
But the problem remains the same.
Is there a way to have header file for Fortran codes? how to declare routines defined in my Fortran file src/LowDiscrepancy.f?
Any help appreciated

[R-SIG-Mac] rnorm.halton
...eveloper/Porting_Guide/ch03.html
, I identify the following changes (Fortran types) to the Fortran
code:
- INTEGER to INTEGER*8
- REAL*8 to REAL*16
The code I would like to change is available on R forge here : http://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/pkg/randtoolbox/src/LowDiscrepancy.f?rev=4229&root=rmetrics&view=markup
Another question I have is how do I tell the R code to use the 64bit
version of my code on 64bit machine?
In the current implementation, the file quasiRNG.R calls directly the
Fortran code with .Fortran.
How could I use the 64bit version direct...

lowercase routine names? manual does mention that.

About Qusi-Monte carlo program
Dear Listers;
Does anybody has experience in doing simulation via Qusi-Monte carlo in R or S-plus, if so, could you like to send a small copy of your program to me, I appreciate and thanks in advance!!
Frankly speaking, I am struggling to write this kind of program, while I could not figure out, painful!!!!!
Best regards,
Tony

Segfault and bad output with fOptions::rnorm.sobol
I have had the following problem with R 2.10, 2.13.1, and 2.13.2, running on
Ubuntu linux 10.04, xubuntu 11.10, and a version of Redhat (I think 5).
rnorm.sobol is producing impossible random values, and occasionally the
routine crashes. Here are samples of the output and the crash message.
library(fOptions)
Zs <- rnorm.sobol(50, dimension=1)
produces this:
[,1]
[1,]
