This has nothing to do with Rcpp.  

The most reliable way is to ... start fresh sessions. 

For which littler and Rscript are useful, so I something like the following
all the time: to test a given package, I load it (option -l or --packages,
takes a comma-sep. list) and exectute a function to test (option -e, or
--eval) via littler's r:

  edd at max:~$ r -l RcppZiggurat -e 'print(zrnorm(5))'
  [1] -1.1409054  0.8759027 -0.1969075 -0.1245053  0.2695581
  edd at max:~$ 

Next time I run this I know I have a fresh session.  RStudio reloads the
current session, and package, for you too.
