Hi, I'm trying to register my native routines using R_registerRoutines (...). I can compile the code, but the loader cannot resolve the symbol: undefined symbol: _Z18R_registerRoutinesP8_DllInfoPK12R_CMethodDefPK15R_CallMethodDefS3_S6 _ $ nm bgx.Rcheck/bgx/libs/bgx.so | grep R_registerRoutines U _Z18R_registerRoutinesP8_DllInfoPK12R_CMethodDefPK15R_CallMethodDefS3_S6 _ Why does it have this funny name? If I look at libR.so, I get an ordinary symbol name: $ nm ~/l...

Hello, The use of .Call and the like all depend on loading shared libraries and registering routines from it. Also, .Primitive and .Internal depend on routines being registered in the R binary. And applications that embed R can override routines declared in Rinterfac.h, but is there a way for an application embedding R to register other routines defined in the application without loading a

Hi, Who should I ask about my package Rigroup_0.83 being moved to Archive status on CRAN and no longer available via install.package? I have no problems with the move if this was simply because of low demand. However, if there was a build issue with the newest releases that caused problems, I would be happy to address it. I'll just ask my students to install it from my own locally hosted

Is it better to wait for complaints (if anyone ever would like to try this package...)? 2. can R_registerRoutines be called more than once within the same library (the same DllInfo data) so that it can reconfigure itself on the fly? 3.

Hello folks, I'm embarking on a project to embed R into the Apache web server, and I'd like your help. Currently, I'm looking for a way for R code to call back into a shared library from which the R shared library was loaded. Essentially, apache starts and loads mod_R.so which runs an initialization routine which calls Rf_initEmbeddedR() and the following code: /* override to

...Interactive = (Rboolean)1; // ptr_R_ShowMessage = Re_ShowMessage; // ptr_R_WriteConsoleEx =Re_WriteConsoleEx; // ptr_R_WriteConsole = NULL; // ptr_R_ReadConsole = NULL; return(0); } int main(int argc, char **argv){ if (embedR(argc,argv)) exit(1); setup_Rmainloop(); DllInfo *info = R_getEmbeddingDllInfo(); R_registerRoutines(info, NULL, callMethods, NULL, NULL); SEXP runner1,runner2; PROTECT(runner1=rexpress("expression({ for(x in 1:5) { .Call('rh_status','x') }})")); if (runner1 == R_NilValue){ UNPROTECT(1); exit...

...more instructive as I do not see much going on in do_detach? suggestions? The library I am working with is in C and uses Nag, it uses the registration facilities, although I have the problem when I do not use the registration facilities. Specifically, I have defined the method: void R_init_DSA(DllInfo *info). However, as I said if I comment this out it appears to behave identically. Also, I have run the whole test case using valgrind to see if I could track down the problem there (I assume I am trashing some of R's memory) however, the only messages I get from valgrind are below - all re...

...ages | namespaces loaded in your R session. OTOH, some packages nowadays have a host of dependencies, so I agree that this at least may happen accidentally more frequently than in the past. The real solution of course would be a code improvement that starts with a relatively small number of "DLLinfo" structures (say 32), and then allocates more batches (of size say 32) if needed. Patches to the R sources (development trunk in subversion at https://svn.r-project.org/R/trunk/ ) are very welcome! Martin Maechler ETH Zurich & R Core Team

...DLLs) 3) We open up the possibility of more dynamic ordering of the LoadedDLL structure. Essentially we can very cheaply move the most recently "used" DLL to the front of the list. The cons, I think, are small in this situation. We already dynamically allocate strings and arrays in the DllInfo strucutre so those are already not memory-local. Additionally, R is frequently operating on large datasets so cache thrashing is almost a given. The negligible time increase in traversing the list, I believe, will be offset by the more dynamic sorting that we are able to give that list. I have w...
