[R] Calling R from C/C++

[root@cdv.dhs.org]

Hi !
I'm totally strange to R. And started downloading/reading dox because my gf. 
is using it in her university project. 
Now the problem sounds like this:
I need to make a module/lib that will allow to call easaly R code/functions 
from C++ (C++ Builder 6). Is it possible without using any intermediate 
things like R-DCOM ?

Please help !

P.S.
Sorry ... no time for RTFM. Any idea/hint is apreciated !
