R help - Aug 2012 - Using R as Shared Library

Hi List, 

I find the following .so file in the R folder of my Arch Linux machine:

,----------------------
| usr/lib/R/lib/libR.so
`----------------------

I copied it to my home folder and changed permissons from root to my
personal user and then tried to call R functions from a different
language (that has a 'native' function to call any kind of Shared
Library on Linux). 

But to no avail - no matter if I try to call 'help' or 'imax2',
I'm
always told the function doesn't exist. 

So my question is basically: whats in there in the libR.so?
Can't I call all core R functions (via 'native') with the same
arguments
as on the R command line? I'm a bit confused now about how to use R as a
shared library on Linux. 

Thanks for any tips.

Let me reformulate my question (since I managed to make 'native' calls
to C functions in libR by now): 
I still wonder whats 'in there' in libR - only the core C functions, or
all the functions written in R itself too? And what packages are included?
