You cannot compile R scripts as a shared library.
You can compile the R engine itself (interpreter and some basic functions) as
.dll (or .so), dynamically load it during run time of your application
and call its low level functions.
All details are in the "Writing R extensions" manual, installed with
Searching Google with "embedding R" gives the following (outdated) link
This says basic things and references the "Writing R Extensions"
You can see the Rgnome sources for example.
