Hi dear R developer, we are trying to build DLL files using Microsoft Visua= l C++. As stated in readme.packages we have to build first the import libra= ry Rdll.lib with the command: lib(def:R.exp/out:Rdll.lib. However, this com= mand gives 2155 errors due to unresolved external symbols (ATTRIB to zlibVe= rsion) in R.exp.Could anybody tell me if something is missing in the comman= d line or

hi everybody, anyone knows how we can transform a binary matrix with TRUE and FALSE to 0 and 1 without looping? Thx --------------------------------- [[alternate HTML version deleted]]

>From the R-2.6.0/doc/README.packages it says: Using Visual C++ ================ You may if you prefer use Visual C++ to make the DLLs (unless they use Fortran source!). The notes here were tested with VC++6. First build the import library Rdll.lib by make R.exp ... In the installation (R-2.6.0-win32.exe) there is no Makefile with an R.exp target that I could find and I get

Hello, I'm trying to compile a library in MS Visual C++ using R.dll. For that, I need R.lib for linking. Where can I get it? "Readme.packages" for R says: "First build the import library R.lib by lib /def:R.exp /out:Rdll.lib" But for this, I need R.exp, that is also not provided with R installation (Lib.exe output: LIB : fatal error LNK1104: cannot open file

Hello, I am trying to compile ROracle _0.5-4 under R 1.9.0 without much success. I am running Windows 2000 SP4, Visual C++ 6.0 SP6, and Oracle client 9.2.0.1.0. I was able to run the pre-compiled version of ROracle_0.5-2 under R 1.7.1, but does not work on R 1.8.1 or R 1.9.0. Here is the output from nmake: C:\Program Files\R\rw1090\library\ROracle\src>nmake Microsoft (R) Program

Hi all, First of all, I found R.exp. Thanks. The following is a paragraph I copied from Venables and Ripley’s book “S programming” on Page242. If the code calls entry points in the R engine, create an import library from the file R.exp in the source-package distribution by lib /def: R.exp /machine: ix386 /out: Rdll.lib and add Rdll.lib to the link command or add it to the libraries to be used

Hi, I am trying to implement on a Win7 box the showArgs example of section 5.10.2 "Calling .External" of the R extension manual. I am using interchangeably gcc (RTools) and Visual C++ (via Makefile.win) to build a package. I get a couple of runtime oddities when the dll compiled with Visual C++. I'd value comments, observations and tips from interested readers. I tried my best to

Hello, The procedure for creating an import library (Rdll.lib) that is documented in gnuwin32/README.packages works fine using the i386 architecture, but it doesn't seem to work under x64. Specifically, the procedure is: pexports R.dll > R.exp lib /def:R.exp /out:Rdll.lib /machine:X86 R.dll There are two issues under x64: 1. Older version of pexports crash when applied to an x64 R.dll.

Hi, I wonder where I can find an example of using a function in LAPACK library in a user's own C code. I wrote a C program which will be compiled and linked to produce a DLL file and then loaded into R. I hope to use a function from LAPACK library, for example, dgesdd, in the program. Following R manual, I call the function by F77_CALL(dgesdd) in the program. The program can be compiled

Full_Name: Venkatesh Mysore Version: R-1.7.0 OS: WindowsXP Submission from: (NULL) (216.165.110.10) While accessing Rproxy.dll repeatedly (using the code from the (D)COM example in the R website) causes a failure in the 24th iteration. R-1.6.2 does NOT give this error. This seems to be a memory management error, that might be linked to the huge leakage difference between R-1.7.0 and R-1.6.2

Dear sir\madam! I'm trying to speed up my R code by writing quite simple dll's in C. But I faced some problems, and I cannot determine their source. #include <Rinternals.h> SEXP mycombin(SEXP N, SEXP k){ int i, *j, *l, c; j = INTEGER(k);l = INTEGER(N); c = 1; if(j[0] > 0 && j[0] < l[0]){ if(j[0] <= l[0] - j[0]){ for(i =

Hi, I am new to R. I need to communicate with Oracle from R program in windows xp. So I am planning to use ROracle. I downloaded the ROracle src from the site below: http://cran.r-project.org/web/packages/ROracle/index.html I am using R version 2.6.2 and Oracle 10g. I followed the instructions to build ROracle. When I try to compile the source src/Makefile.win I get the following error:

recently I used gcc 4.9.1 (http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win64/Personal Builds/mingw-builds/)on windows to build R,but failed when link R.dll ,it report linker status 5.  after some digging, I found when use gcc 4.9.1 64 bit on windows there are lots of .refptr.*(* is r function name) in R.def, which lead build fail.so I add a simple path to

Hi all, and thx a lot for your answers, in fact i know that R deals with logical numbers 0 and 1 the same way like TRUE and FALSE but my problem is in fact with C language. I have done an interface with C and my first problem was with float variables, but this warning doesn't appear everytime and really i don't know the problem with R: "Warning message: DLL attempted to change

Hi Simon, Thanks so much for your help. Your advice has been taken to heart. I now pass in blocks of 100,000 records, and it does 100,000 predictions in seconds and returns a logical vector with the predictions to an int array. It works like a charm! I want to reference what we were talking about earlier. Let?s say we evaluate an R expression. Is there a way to just print, verbatim, what R

I would like to be able to compile and link the following two program into native executables. These are a vastly reduced testcase, so ignore for a moment the fact that the native compiler driver might have default -L/-F search paths and -lSystem by default. $ cat test1.c extern char *zlibVersion(void); extern int puts(char *); int main(int argc, char *argv[]) { puts(zlibVersion());
