Have you looked RInside which covers your use case 

    - accessing an embedded R instance from an outer C++ program
     
    - sending data and/or parameters to R,

    - evaluating R expressesions

    - getting data back from R to the C++ layer

See 

    http://dirk.eddelbuettel.com/code/rinside.html 

for more.  Documentation is still sparse, but there are examples, and the
Rcpp classes are very useful for converting a number of basic R types to and
from C++ representations.
