Hello,
This was discussed this week in the thread "LinkingTo and C++".
It is possible, and documented in WRE section 5.4 :

Hi the list,
In a package P1, I write a function f1 in C, potentially an internal
function (not to be called from R).
In a package P2, I write a function f2 in C. The f2 function needs to
use f1 from P1. Is it possible ?
--- 8< ---- In file P1.c ---------
double f1(x,y){
....
}
--- 8< ---- In file P2.c ---------
void f2(x,y,z){
double result;
....
result = f1(x,y);
....
}
Thanks
Christophe
