Calling C++ code fom R --How to export C++ "unsigned" integer to R?
...o the following in C++:
int Some_INTEGER = 5;
int *p_myInt;
SEXP myInt;
PROTECT(myInt=NEW_INTEGER(1));
myInt[0] = Some_INTEGER;
UNPROTECT(1);
return myInt;
However, it appears that myInt is a signed integer.
I have looked over Rdefines.h and it does not look like there is a
definition for NEW_UNSIGNED_INTEGER !
How would I export an unsigned integer to R?
obviously this won't work:
unsigned int Some_INTEGER = 5;
unsigned int *p_myInt;
SEXP myInt;
PROTECT(myInt=NEW_INTEGER(1));
myInt[0] = Some_INTEGER;
UNPROTECT(1);
return myInt;
This would give me a casting error!
How should I get arou...
