Correct -- the RInside package comes with four example directories.
And each of these four directories has a Makefile. The easiest to start with is
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.
