similar to: using compiled fortran in R

I am trying to use dynamic loading of an outside C routine. I am attempting 6.12.1 of Phil Spector's book. When I try to load the object file I get an error I don't understand: > dyn.load("runa.o") Error in dyn.load(x) : unable to load shared library "/usr/home/tdlong/run_avg/runa.o": /usr/home/tdlong/run_avg/runa.o: ELF file's phentsize not the expected

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

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 am wondering if anyone has had experience w/the R database packages: RMySQL, RODBC, RPgSQL, and/or RmSQL, and if so, if you have any recommendations to make. We have some large tables we would like to store -- something like 5-10 columns by 3.5 mil rows (or maybe 7 mil rows). thanks, Natalie Hawkins Statistical Research Associate FHCRC/Scharp

Dear R-devel, I would like to launch the Rgui.exe from a Fortran console application (we will call this FortranCon.exe), that I have written myself. To do this, I send the command line "C:\Program Files\R\R-X.X.X\Rgui.exe" (where X.X.X is the version number) as an argument to the Windows API function CreateProcess (see http://msdn.microsoft.com/en-us/library/ms682425(VS.85).aspx)

Hi All, I'm running R 0.63 on Redhat 5.1 and when I attempt to load a fortran routine I get: > dyn.load("/home/royle/Rstuff/varna.o") Error in dyn.load(x) : unable to load shared library "/home/royle/Rstuff/varna.o" this function varna.o was compiled with: gcc -c varna.f with no errors or warnings. Does anyone have any thoughts on this? Thanks! (and thanks to

Good Afternoon R Help! On of my users is seriously thinking about moving to R from Splus. In his testing, he has already found some benefits to it. He has, however run into one issue, calling his Fortran functions in R. Previously, in Splus, he would do the following: 1. Compile via f90 the *.f program 2. link the object file to the Fortran IMSL libraries via the 'ld' command 3.

Hi all, I'm working out some Fortran code for which I want to compute the Choleski decomposition of a covariance matrix in Fortran. I tried to do it by two methods : 1) Calling the lapack function DPOTRF. I can see the source code and check that my call is correct, but it does not compile with: system("R CMD SHLIB ~/main.f") dyn.load("~/main.so") I get: Error in

I used "R CMD SHLIB" to compile the fortran filename.f file and the filename.so is generated. But since in filename.f it calls another subroutine written in C, i had problem in "dyn.load" because it could not find the C subroutine. I have the .c file but don't know how to tell R about it. How should I compile when I want to call the fortran function

Dear all, I'm trying to compile FORTRAN code to be used in R, failing miserably. I got a simple code function to try to figure out what is going wrong. Here is the code (available on the web) : subroutine bar(n, x) integer n double precision x(n) integer i do 100 i = 1, n x(i) = x(i) ** 2 100 continue end 1. I compiled the

Hi, can anybody point me to a package with C++ code that call Fortran subroutines? I am trying to do the same thing but we scarce success.

Hello everybody, Could someone please send me a very simple example using Fortran from R? Say pass a value to an executable and get the result in R. Actually it seems it may be possible to call an *.f file ?? or I am wrong again? The manual is very terse on the subject. Thank you very much Stephen Elijah -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help

In the following code routine 'initaquaphy' is defined in Fortran, and dynamically loaded into R.: test.f: subroutine initaquaphy(odeparms) external odeparms double precision pars(19) common /myparms/pars call odeparms(19, pars) return end $ R CMD SHLIB Aquaphy.f gfortran -fpic -g -O2 -c test.f -o test.o gcc -std=gnu99 -shared

Hi, here are a couple of strange things happening with R.2.2.0 compiled under Mandrake-10.1 At the begining of the story I have segmentation fault using package RandomFields in conjuction with some Fortran code of mine loaded with dyn.load. One of my fortran programs contains a subroutine named fstat Trying to trace , I simplified the sequence as much as possible and I end up with the the

Is it possible to run Fortran 95 code from R? I don't think so, but hopefully someone can prove me wrong. Here is the test I tried: A little fortran 95 subroutine: subroutine allloc() real, dimension(:, :), allocatable :: a integer :: n n = 10 allocate(a(n,n+1)) end I then compiled: >g95 -c allloc.f >R CMD SHLIB allloc.o Here is what happens when I try to dyn.load it in R 2.1.0

Dear all, I would like to call TLNise ("Two-Level Normal indipendent sampling estimation") software within R. This software estimates a hierarchical model and it can be download from Philip Everson's website at "http://www.swarthmore.edu/NatSci/peverso1/TLNise/tlnise.htm". The TLNise software consists of: 1) a Fortran source code (tlnisemv1.f) and 2) a Splus code

Hi, I'm learning Fortran and trying to load a Fortran subroutine into R. I've done: R SHLIB Fibonacci.f and it compiled fine. Then I went into R and done: > dyn.load("Fibonacci.so") > Fib <- function(n) { + .Fortran("Fibonacci", + as.integer(n))[[1]] + } > Fib(5) Error in .Fortran("Fibonacci", as.integer(n)) :
