Hello, everybody, I met a big problem. What I want is to use c code in R. I have load a test code "conv.c" in R and run it successfully. However, in my real code, I use matlab c library (Matrix Inverse function). After I use command "R CMD SHLIB" to share library, I can not use "dyn.load" to load the object in R. "undefined symbol:

Hello all. I'm developing a package for R holding a Gibbs sampler, which tends to have better performance when written in C than in R. During each iteration in the Gibbs sampler, I need the inverse of a symmetric matrix. For this, I wish to use lapack, as is concisely suggested in "Writing R extensions", since this will have better performance than I could ever write myself. After

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

Hi, I am working on a UNIX machine and I am interfacing R and C with the .C function. I am trying to call LAPACK and BLAS routines, but am running into a problem where, while I am able to run the BLAS routines, I cannot run the LAPACK routines. I compile my .c file (at end of email) in the following way: [mhitczen at jlogin2 ~/Cstuff]$ R CMD SHLIB testmore.c gcc -std=gnu99

Dear all, I have done every step as the previous mail. 1. unpack tools.zip into c:\cygwin 2. install Active perl in c:\Perl 3. install the mingw32 in c:\mingwin 4. add "c:\cygwin; c:\mingwin\bin" in "Control Panel -> System -> Advanced -> Environment Variables -> Path -> Variable" , and they are in the beginning of the "Path" Because I install R in

Dear all, I really appreciate your help.

Dear Gabor, Thank your for helping me so much! I have loaded R the newest version 2.1.1. Then I setup it in the path of D:\program files\R\ 1. unpack tools.zip into c:\cygwin 2. install Active perl in c:\Perl 3. install the mingw32 in c:\mingwin 4. add "c:\cygwin; c:\mingwin\bin" in "Control Panel -> System -> Advanced -> Environment Variables -> Path ->

Dear Thomas, thank you for your input. I've debugged one of the packages and I confirm that the breakage is related to passing of strings from C to Fortran. Indeed, BLAS and LAPACK define a large number of subroutines that take one or more explicit single-character strings as arguments. Other than that, BLAS has only one function (xerbla), which takes a string of unspecified length,

Hello everybody, Could I consult you a question? I always use R old version 1.9.1 . Because I can not add my library into the new version 2.0.0 by the same method as old version. * I have read the webpage <http://www.stats.ox.ac.uk/pub/Rtools> * Download the tools.zip * Unpack tools.zip into c:\cygwin * Install Active Perl in c:\Perl * Install the mingw32 port of gcc in c:\mingwin *

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

hi all, i posted a question before about this, but i may have been too cryptic to understand. in short, there exists an R package that someone is writing. this package depends on a custom library (written in C,), compiled as a shared, and called by the package's functions via the .Call(...) method. we are testing out different code implementations of the compiled library functions, and thus
