Embedding R in C application

I have done this and it sounded like all that I needed to do is 
#include <R.h> to get access to R functionality.  However, I was 
getting compiling errors when attempting to make an R function call 
directly from C, so I did some research, and this is where I saw the 
reference to needing the libR.so.  By just including R.h, does this 
provide me with the same R functionality as the references that I saw 
about the libR.so? If so, then I will continue to use this to access 
the R functionality and use the "Writing R Extensions" manual.

Thanks,

To whom it may concern,
I am very interested in embedding the R functionality in our 
application. This is a C application that currently runs on Win32, 
but will also run on Linux in the future. From the material that I 
have seen, I need R compiled as a shared library to evaluate R 
expressions from C. Is this correct? If so, can I download this 
shared library

from

somewhere? Is there any API document pertaining to this shared

library?

You want to look at the "Writing R Extensions" manual, in particular 
the

chapters on the R API (for access to the underlying computational
routines) and the one on linking GUIs or other front-ends (which 
sounds more like what you want to do).
