(Tried this query on r-help with no luck, maybe someone here can help?) I would like to call the 'RFinalizerEx' function that appears in Rinternals.h using ".Call". It worked for me in the past, but now I get an error message something like: 'call function name not in call table'. I'm using the 1.6.1 rpm from CRAN. Anyone know what's going on? Thanks.

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...

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, whic...

Hi, Consider the following file. ******************************* foo.cc ******************************* #include <R.h> #include <Rinternals.h> #include <iostream> ******************************* R CMD SHLIB foo.cc gives scads of errors. I've use C++ extensively with R before (using C linkage) but not with Rinternals.h. I'm puzzled. The errors make no sense to me. Am I doing something wrong? Is it impossible to use...

Hello everyone, I try to write a c++ code which calls embedded R and uses some of R internal functions. What I read is just lots of macro names defined in the Rinternals.h or Rdefines like R_Parse, Rf_install and so on. But where can I get the detailed information about the parameters of these macro? For example, what about the parameters of SEXP R_ParseVector(SEXP, int, ParseStatus *)? Thank you very much! Baiyi Song Computer Engineering Institute Dortmund...

Hi all, I would like to determine if an ALTREP object is from my package, I see there is a function `ALTREP_CLASS` defined in RInternal.h but its return value is neither a `R_altrep_class_t` object nor an STRSXP representing a class name. I do not know how to correctly use it. Any suggestions? Thanks, Jiefei [[alternative HTML version deleted]]

Hi, R_tryEval, exported in Rinternals.h but not part of the API, is currently defined as: R_tryEval(SEXP e, SEXP env, int *ErrorOccurred); I'm trying to embed R in an application (basically yet another GUI), and this has been very helpful to catch errors. It would be even more helpful if it also gave access to the visibility flag...

...I've managed to to most of what I want, but I have one remaining question and a suggestion. The suggestion first: I've found it useful to put #ifdef __cplusplus extern "C" { #endif and #ifdef __cplusplus } #endif around the function prototypes in Rinternals.h (in /usr/local/lib/R/include on my Red Hat 7.2 box) so my dynamic linker would no longer complain about mangling-related undefined symbols. Also, I had to use #define USE_RINTERNALS before including them in order to get a few macros I suppose are natural to use. To be honest, I do think the inclu...

...I'm trying to write a gui program that accesses some R code I've written. The gui is written in c++ and includes qt libraries and vigra libraries (for image manipulation). Unfortunately I've been getting dependencies due to constants getting redefined within the R.h/R_ext library and Rinternals.h. I tried rewriting the R interface but the problem keeps propagating. I've been told Gnumeric is a better gui library for working with R however, before I rewrite my entire program, is there an obvious solution to calling R functions in C++/qt? Thanks.

I have created a DLL not so long ago using C code. My code used the IntegerFromString() function that used to be exported in the Rinternals.h header file (and thus easily accessible). Recently I upgraded to R 2.5.0 and my DLL stopped working. I see that the IntegerFromString() function is not exported in any of the header files in the RHOME\include directory. Is it possible for me to use it without installing all R source files? I can...
