[Rd] 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.

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).
