Correct -- the RInside package comes with four example directories.

And each of these four directories has a Makefile.  The easiest to start with is

   examples/standard/Makefile

as you can simply drop in a new file 'myhelloworld.cpp' (or any other name
you choose) into this directory and say 'make myhelloworld' --- and the
binary 'myhelloworld' will be created for you.

It does this by querying R via Rscript to learn about 

   headers and libraries for R

   headers and libraries for Rcpp

   headers and libraries for RInside

and all six components are needed for compiling and linking.
