too many arguments in foreign function call
Hi all,
I've just been working with a piece of fortran code (Leo Breiman's
random forest code) that needs a lot of arguments. When I use .Fortran,
I get the message 'too many arguments in foreign function call'.
Neither the help page for .Fortran (actually Foreign) nor "Writing R
Extensions" explains how many arguments are too many.

segfault with grid and null unit (PR#8014)
Full_Name: Jonathan Paisley
Version: 2.1.1
OS: Mac OS X 10.4.2
Submission from: (NULL) (81.178.107.67)
I was following an example from library/grid/doc/grid.pdf ("Introduction to
grid") and had the following code, where I'd mis-typed 1,3 instead of 1,2 as the
first arguments to grid.layout.
Sourcing this code causes the R GUI to crash. I've enclosed a partial backtrace

Invalid read of size 8
Hi,
I have a R program that call a C function. I define a vector of pointer as
int nLC=3;
int pownLC = nLC*nLC
double *MatCovExtra[nT+1];
for(k=0;k<K+1;k++)
{
MatCovExtra[k] = (double*)R_alloc(pownLC, sizeof(double));
}
where nT>K. Then i put some values on the vector associated with the
pointer:
for(k=0;k<K+1;k++)
{
for(i=0;i<nLC;i++)

must .Call C functions return SEXP?
For using R's .Call interface to C functions, all the examples I've
seen have the C function return type SEXP. Why? What does R actually
do with this return type? What happens if I *don't* return a SEXP?
Reason I ask, is I've written some R code which allocates two long
lists, and then calls a C function with .Call. My C code writes to
those two pre-allocated lists, thus, I

.Call not counting parameters consistently (PR#8450)
The R_registerRoutines C function allows the number of parameters to a
.Call function to be registered. For example, the tools package
function md5sum() calls "Rmd5", which has been registered to require
just one parameter.
But if it is called with the wrong number of parameters, only the first
error gets caught:

capturing value of C or Fortran function
Re: src/main/dotcode.c:do_dotCode()
The value, if there is one, of a function called by .C or .Fortran is not
captured, so one needs a wrapper. To avoid that, the user would have to
declare that there is a value, specify its type, and supply an R variable
to hold the value. Presumably, all of these could be combined in a new
"VALUE=var" parameter. Then do_dotCode could arrange the

implementing a foreign system with system?
Hi-
There is a public doman geostatistics package used in the minieral industry called GSLIB and I would like to use it from R. However it is fortran (but portable and easy to compile on windows and linux)and has its own file format and control file format. It seems easiest to write an r function to dump r data to an ascii file, build a control file in ascii; call the GSLIB program with

Spare some CPU cycles for testing lme?
If anyone has a few extra CPU cycles to spare,
I'd appreciate it if you could verify a problem that I

completion.

Qs on calling R from C
Consider the following simple C program:
/*** hello_r.c ***/
#include <Rinternals.h>
SEXP hello() {
return mkString("Hello, world!\n");
}
int main(void) {
SEXP x = hello();
return x == NULL; /* i.e. 0 on success */
}
This program segfaults:

segfault on Sparc Linux (RH6.0)
We are having problems building R on Red Hat Linux 6.0/Sparc.
R compiles with no problem but then it fails "make tests".
Specifically, the line
eigen(cbind(-1,c(1:2,0),0:2)) # complex values
causes a segmentation fault. Previous versions of Red Hat Linux
did not give this problem.
The eigen() function is one of the rare cases in the base library where
Fortran code is called via the

R-alpha: eigen and batch
Batch:
Putting q(save=F) at the end of my file does not work in my
context because I can no longer source the file without quitting. I
have that quit statement in my .First so that I always quit that way
interactively. The problem is that it is ignored in batch.

Can anyone spot the problem here. Following is an edited script of the install

Easily remedied (or at least, such that compiles without error message ... )

help debugging segfaults

Hi everyone,
I've run into segfaults when using my randomForest package on large dataset
(e.g., 100 x 15200) and large number of trees (e.g., ntree=7000 and
mtry=3000). I'm wondering if anyone can give me some hints on where to look
for the problem.

[patch] Behavior of .C() and .Fortran() when given double(0) or integer(0).
Dear R-devel,
While tracking down some hard-to-reproduce bugs in a package I maintain,
I stumbled on a behavior change between R 2.15.0 and the current R-devel
(or SVN trunk).
In 2.15.0 and earlier, if you passed an 0-length vector of the right
mode (e.g., double(0) or integer(0)) as one of the arguments in a .C()
call with DUP=TRUE (the default), the C routine would be passed NULL

.Call and Segmentation Fault
Hello to everyone!
I use .Call to call a C function without arguments wich calls a
fortran optimization package. My C function uses others C and Fortran
functions and it works fine when I call it from a main() in a C
program. But when I call it from R with
.Call("name_of_the_c_function"), R gives me some weird output.
This weird output is a worng answer to my optimization problem
