Using R 2.0.1 on Windows XP, I am getting an error msg: Error in .Fortran("conic", nxy = nxy, npt = npt, CP = cp, EP1 = ep1, EP2 = ep2, : Fortran function name not in load table I am wondering if there is a way to see what function names are in the load table? Maybe the function name has been altered? The first thing I do in my analysis script is to load a DLL, conic.dll,

Hi! I would like to call a Fortran subroutine within R. For doing this, I first built a shared library for loading into R under Unix and it was successful. But when I tried to load a shared library using dyn.load() function for use in .Fortran(), I got an error message. The command I input below in R is: >dyn.load("aaa.so") The reslut is: error in

Dear All: Now I am writing program in delphi , found it is very convenience to do anova, T-test, F-Test, etc in R , how to call R in delphi? Thsnks.

...involved in shared libraries. I get the impression however that I'm missing something about Windows DLLs. Compulsory version information: OS: Windows XP SP2 R: 2.8.1 GCC: 4.2.1-sjlj (mingw32-2) (From Rtools29.exe) For the record, I've read http://www.stats.uwo.ca/faculty/murdoch/software/compilingDLLs/readme.packages.txt which hints at some requirement for DLLs to use _cdecl. I've started exploring along this line, but there's a lot of documentation to trawl through to make sense of it all and I don't want to go off chasing a red herring if I just need to pass a special --make-it-w...

Hello, I used a mac G5, R.2.1.1, and G77 3.4.4 and I would like to use and call a fortran subroutine. The trouble is that it seems I am not able to correctly load the compiled code. Here is what I have done: In the terminal this how I compiled my fortran code: R CMD SHLIB ~/Desktop/Fortan_kmeans/kmeans3.f There is the wrapper I have paste inside de kmeans3.f file: c

Hi, I am having problems calling a fortran routine from within R. When the routine is called, R exits with an application error: "The instruction at 0x004a8b7d referenced memory at 0x200000015. The memory could not be written". The R code used to call the routine is: .Fortran("GTEST",a=as.integer(1),b=as.integer(3),c=as.integer(-10),d=as.inte ger(0),e=as.integer(0)) The

Dear R-listers, I have created a "dll" and I call it from a R function. However R stops and shows the message: "Unhandled exception in Rgui.exe (R.DLL): 0xC0000005: Access Violation" I get this error in other situations and I solved it verifying that all parameters are called fine. (e.g., double precision -> as.double, integer -> as.integer,...). I have verify this.

Dear all, I'm studing how to include .c code in my .r functions . In the R-exts.pdf manual I have found the following code. At one point the author write "called from R by"... How can I load a .c file on R? ( I am using a xp windows as so.) Thank you ale void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0; i < nab; i++)

Hi, there, I have a number of F90 codes wish to be linked into R under Windows XP OS. Do anyone know how to do it and give some advice? Many thanks. Hanson

Hi, all: I want to call a c program in the windows version R, so I compiled it in VC to get the dll file and use the command ?dyn.load? to call it in R. There is no error appeared for this command, but when I use the command ? is.loaded? to check, it shows that dll file isn?t be loaded. Does anyone have same experience or know the correct way to do it? Best wishes, Guan Xing 5/22/03

Hi everyone, I've created a dll for a fortran subroutine, and when I call the subroutine in R (via a wrapped function) a standard program shutdown windows error prompt immediately pops up: the program has encountered a problem and needs to be shut down... send message / don't send message to MS... etc. When I click "Don't send", the R consol does not then shut down, and

Hello My question is the following. I have tried to find a similar subject in archives but not found (perhaps bad search!) and I tried R-help and I was advised that R-devel would perhaps better for my question So I wonder if it is possible to create a dll from a R code to use it in another language/program. Indeed, one of my colleague wrote a R code combining some R functions to create a

Sir/Madam, I am a graduate student in Petroleum Engineering. I have a problem in using R and hope that you could help in solving that. I have a code in C, which displays orthogonal arrays when I give number of rows and number of columns to it. I have another code in R that calls this C code. I am very new to R. I downloaded the R and loaded packages base and mva. I also kept my C code .exe

Anybody out there successfully using the Salford Fortran compilers with R? I have created a DLL using the Salford FTN95 compiler and it works in as far I can dyn.load it, run the routines and get the right answers back. Unfortunately subsequently, sometime later, the Rgui crashes (access violation I think from the DrWatson log). The crashes depend on whether or not I paste the code as one

Hi, I am hoping some one can help me. I am learning to use C and would like to learn how to call c code in R. I have look at Writing R Extensions and I tried to copy the example on page 38 void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0; i < nab; i++) ab[i] = 0.0; for(i = 0; i < *na; i++) for(j = 0; j <

I have some C data I want to pass back to R opaquely, and then back to C. I understand external pointers are the way to do so. I'm trying to find how they interact with garbage collection and object lifetime, and what I need to do so that the memory lives until the calling R process ends. Could anyone give me some pointers? I haven't found much documentation. An earlier message

We are trying to compile and run the ttest.c example that comes with R (in C:\Program Files\R\rw1081\src\library\windlgs\src\ttest.c). After compiling it with MS Visual C++ we load the DLL with dyn.load. So far it seems good, but when we try to call it from R (after running C:\Program Files\R\rw1081\src\library\windlgs\R\windlgs.R) R crashes. We have tried changing the exports from DLL but have
