similar to: interfacing C++ using .Call

Dear All I'm currently developing a package for R (1.9.0) on Win32, with C++ source code. Having followed the instructions in readme.packages, my code compiles fine with R CMD SHLIB (as well as R CMD check) ... until I start using the internal R functions. (Interesting: Rprintf seems to be the exception.) For instance, the following code compiles fine: #include <R.h> #include

I've been trying to create/load/call a dll from R-1.8.1 on Windows without much success. I've been able to at least load the library on FreeBSD (1.8.1). I've been able to perform this before using DLL that weren't created using RCMD SHLIB, but simply compiling under MS DevStudio. C:\optflikam>rcmd shlib --output=optflikam.dll as47.f as197.f flikam.c g77 -O2 -Wall -c as47.f

Hello, I've noticed that with g++ 4.3 I get the following "warning: deprecated conversion from string constant to ?char*?" when I call e.g., Rprintf("Hello world"); or when I try to define a const char e.g., char lower = 'L'; I am wrapping the c++ code in extern "C" {}. This seems to be something new with g++ 4.3, because the same code compiled

Hi all, I am wondering if anyone has problem installing 'knncat' package. I tried to install using 'Rcmd INSTALL knncat_1.1.1.tar.gz', error message appeared. I attached the message in the end. I allso tried to install from RGui, but it was not listed. Thanks in advance. Regards, jenny ---------- Making package knncat ------------ adding build stamp to DESCRIPTION

Hello everyone, I've just attempted to build R-1.4 on Compaq Tru64 (I'll enclose the text from bug.report() from R-1.3.1 at the end.) The relevant part of the log is below. Any ideas? gcc -shared -o methods.so do_substitute_direct.o methods_list_dispatch.o method_meta_data.o slot.o -L/usr/local/lib /usr/ucb/ld: Warning: Unresolved: TYPEOF Rf_error Rf_protect Rf_substitute

Hello! I'd like to ask you a question about c (macros): In Rinternals.h are defined: a) SEXP Rf_protect(SEXP); b) #define protect Rf_protect c) #define PROTECT(s) protect(s) As far as I understand the calls Rf_protect( x ), protect( x ) and PROTECT( x ) are all equalent. So whats the reason that there are 2 macros defined? Why 3 times the same when 1 distinct function would be

R users, I recently upgraded (?) to Windows XP from 2000. I am trying to build an R package. I have done this many times on my old system and I am not sure why it is not working in XP. To build the package I call a bat file that specifies all the necessary paths -- but the "build" file (which appears to be a perl script) is looking for a "src" subdirectory in the src

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

Hello, I wrote an R function and want to build an R package on winXP. I have set my path:C:\bin;C:\MinGW\bin;C:\Perl\bin\;C:\Tcl\bin;C:\texmf\miktex\bin;C:\Program Files\R\rw1081\bin; I tried to run "Rcmd build --help" but failed.

There seems to be a latent flaw in the definition of struct SEXPREC in Rinternals.h, which likely doesn't cause problems now, but could if the relative sizes of data types changes. The SEXPREC structure contains a union that includes a primsxp, symsxp, etc, but not a vecsxp. However, in allocVector in memory.c, zero-length vectors are allocated using allocSExpNonCons, which appears to

As I mentioned in my previous message about speeding up evalList, I've been looking at ways to speed up the R interpreter. One sees in the code many, many calls of PROTECT, UNPROTECT, and related functions, so that seems like an obvious target for optimization. Indeed, I've found that one can speed up the interpreter by about 10% by just changing these. The functions are actually macros

Hi, I've just tried to run example-3 from Friedrich Leish. I'm using R 1.8.1 and MiKTeX 2.2 on Windows XP.

Dear R-ers: Recognizing that it is better to remain silent and have people think you stupid than to speak and remove any doubt, I fear that I must speak nonetheless. I am having the Devil's own time trying to make a simple R package for my own use. Yes, I have perused the FAQs and searched the archives. Yes, I have read "Writing R Extensions" and eventually divined what Rcmd

First . . . SUBSCRIBE (I want to subscribe to the list). Second, I am trying to install R on windows XP. In looking at the instruction manual I get the following: The simplest way is to use 'rw1081.exe' or 'miniR.exe'. Just double-click on the icon and follow the instructions. If you installed R this way you can uninstall it from the Control Panel. How do I get the
