The general approach is described in the 'R Extensions' manual and sometimes
discussed on the r-devel list.  It is somewhat error-prone.

So have a look at

which very much describes your use case.  

The initial build is currently a little too hardcoded (but works out of the
box on Debian / Ubuntu in 32 and 64 bit). I need to add some more autoconf
logic to copy with slighly different directory structures on eg Fedora 64bit.

If you don't want to embed R, then Simon's Rserve is an excellent alternative.
