thanks. that's a nice tutorial, but what i'd really like to do is write a program with R embedded in it (and not have to load the interpreter). i found some documentation for doing that here: http://cran.r-project.org/doc/manuals/R-exts.html#Embedding-R-under-Unix_002dalikes now i'm going through the tests/Embedding directory (included with the R source distribution). i've gotten Rtest.c to compile with: $ R CMD SHLIB Rtest.c gcc -I/usr/lib/R/include -I/usr/local/include -D__NO_MATH_INLINES -mieee-fp -fPIC -march=pentium4 -O3 -pipe -fomit-frame-pointer -c Rtest.c -o Rtest.o gcc -shared -L/usr/local/lib -o Rtest.so Rtest.o -L/usr/lib/R/bin -lR then when i try to run Rtest.o, i get: -/bin/bash: ./Rtest.o: cannot execute binary file Rtest.c contains: #include "embeddedRCall.h" int main(int argc, char *argv[]) { eval_R_command("print", argc, argv); return(0); } embeddedRCall.h contains: #ifndef EMBEDDED_R_CALL_H #define EMBEDDED_R_CALL_H #include <Rinternals.h> int eval_R_command(const char *funcName, int argc, char *argv[]); SEXP Test_tryEval(SEXP expression, int *errorOccurred); void init_R(int argc, char **argv); #endif i also get the "cannot execute binary file" error when trying to compile and run the following code from the documentation: int Rf_initEmbeddedR(int argc, char **argv) { /* This is already compiled into R */ Rf_initialize_R(argc, argv); setup_Rmainloop(); return(1); } int main(int ac, char **av) { /* do some setup */ // Rf_initEmbeddedR(argc, argv); /* do some more setup */ char *argv[]= {"REmbeddedPostgres", "--gui=none", "--silent"}; Rf_initEmbeddedR(sizeof(argv)/sizeof(argv[0]), argv); /* submit some code to R, which is done interactively via run_Rmainloop(); */ end_Rmainloop(); return 0; } what am i doing wrong? ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
