Practice Activity 8: A Package from Scratch

Part One: A basic package

Return to R Packages Chapter 1 - The Whole Game, but this time, instead of only reading through, follow the steps in the chapter to actually build your own copy of the regexcite package.

For full credit, you must commit your code frequently throughout this process, so that it is clear you did not simply copy the complete package.

Part Two: Adding to the package

Download this .R file and then add it - without editing anything about it - to the tests/testthat/ folder of the regexcite package.

Re-run the package tests. You will see that the newly added tests all failed, because they tested functions that do not exist!

Look at the source code for these unit tests, and use this as a reference as you write the new functions into your regexcite package. Make sure to properly document these new functions using roxygen2 comments.

Once your package passes all unit tests, make sure everything is pushed to GitHub, and turn in the GitHub URL.
