These are basic questions that are addressed by, inter alia, 

      - the R Extensions manual

      - examples among the 2300+ packages on CRAN

      - books such as V + R's "S Programming", Gentleman's "R Programming for
        BioInformatics" (which is not about BioInformatics) or Chambers
        "Software for Data Analysis"

But it is off-topic here.  

You need to teach yourself the mechanics of doing a package with one function
calling one C or C++ function.  

Once you grok that, try one that calls an external library. Once you grok
both those aspects come back to RcppArmadillo.

You are fighting too many moving parts at once.
