Dear Stephanie, Have a look at the testthat package and the related article in the R Journal.

I use a package to contain simple functions that can be handled by unit tests for correctness and more complex functions that combine the simple functions with business logic. Where there are proposals to change either the simple functions or the business logic, a sample needs to be run before the change and then after it to understand the impact of the change. I do this currently by 1. Using Rmarkdown documents 2. Loading the package as-is 3. Getting my sample 4. Running my sample through the package as-is and outputting table of results 5. sourceing new copies of functions 6. Running my sample again and outputting table of results 7. Reloading package and sourceing different copies of functions as required I really don't think this is a good way to do this as it risks missing downstream dependencies of the functions I'm trying to load into the global namespace to test. Has anyone else had to do this sort of testing before on their packages? How did you do it? Am I missing an obvious package / framework that can do this?
