...ith the R math library hangs. Note that set_seed is defined as taking two unsigned int arguments, so 0's are valid arguments. I'm guessing that since 0 is as low as an unsigned integer can go, it represents some kind of edge case. ################################################ #define MATHLIB_STANDALONE #include <Rmath.h> int main(void) { set_seed(0, 0); rgamma(1, 1); } ################################################ If I add the definitions of `get_seed` and `set_seed` from `src/nmath/standalone/sunif.c` to my code, then the hang disappears. ######################################...

Hi, I want to use R_qsort_int_I() in my C function, but getting the following error.

...is that right? I also wanted to use some of the functions in the Rmath library in the same program. However, when I use it, I get an error in the header files. which says essentially that there are some redeclarations in the header (specifically, Rboolean, TRUE and FALSE). I have defined #define MATHLIB_STANDALONE 1 is there anyother preprocessor directive I should give and define other things needed?

This packages provides the libRmath shared and static libraries which can be called from standalone C or C++ code. Well, I use runif() function in test_runif.c: #include <Rmath.h> main() { // ...
