Problem with Rboolean in c++ code
I am trying to use R_RegisterCFinalizerEx to ensure some c++ object is properly deleted after use. However, I run into some problems when trying to pass in the third argument which is an Rboolean. The line 'R_RegisterCFinalizerEx(p, finalizer, TRUE);' generates the following error when trying to compile using R CMD SHLIB: g++ -I/usr/share/R/include -DNDEBUG -fpic -O2 -pipe -g -c rboolean.cpp -o rboolean.o rboolean.cpp: In function ?SEXPREC* create(SEXP)?: rboolean.cpp...

Speeding up sum and prod
...gest reason for the improvement is that the current code (in 2.11.1 and in the development release of 2010-08-19) makes a costly call of ISNAN even when the option is na.rm=FALSE. The inner loop can also be sped up a bit in other respects. Here is the old procedure, in src/main/summary.c: static Rboolean rsum(double *x, int n, double *value, Rboolean narm) { LDOUBLE s = 0.0; int i; Rboolean updated = FALSE; for (i = 0; i < n; i++) { if (!ISNAN(x[i]) || !narm) { if(!updated) updated = TRUE; s += x[i]; } } *value = s; return(upd...

Possible changes to connections
When I originally implemented connections in R 1.2.0, I followed the model in the 'Green Book' closely. There were a number of features that forced a particular implementation, and one was getConnection() that allows one to recreate a connection object from a number. I am wondering if anyone makes use of this, and if so for what? It would seem closer to the R philosophy to have

syntax error in memory.c when building R-devel on AIX
...any problems. I used the settings in the Appendix B of R-admin, using the set of variables that Tim Hoar used (i.e., trying to build 64-bit R using native compilers). configure ran fine, but `gmake' gave me a syntax error when compiling src/main/memory.c. The offending line seems to be: Rboolean success = FALSE; Can anyone provide pointers? (Just to make sure, I tried building it on our SLES9-x86_64 box, and that passes make check.) TIA! Andy

parallel::mc*: Is it possible for a child process to know it is a fork?
When using multicore-forking of the parallel package, is it possible for a child process to know that it is a fork? Something like: parallel::mclapply(1:10, FUN = function(i) { test_if_running_in_a_fork() }) I'm looking into ways to protect against further parallel processes (including threads), which not necessarily are created via the parallel:mc* API, are being spawned off recursively.

Emulating a REPL in frontends
...API. If there is a concern that the details of this function may change, a wrapper like the following should be good enough for most, if not all frontend purposes: void Rf_parseErrorDefault() { parseError(R_NilValue, 0); } 2) Add a simple function to do auto-printing to the public API. E.g.: Rboolean Rf_doAutoPrint(SEXP exp) { if(R_Visible) { printValueEnv(exp, R_GlobalEnv); return TRUE; /* was printed */ } return FALSE; } Another suggestion, which might well be seen as adding too many constraints on future development, but provided for completeness: A more generic version of t...
