Reading for 2017-10-05

Today’s class will introduce the basic idea of an R package as a fundamental unit for sharing re-usable R functions. We will re-organize our population dynamics assignment repo into the structure required for an R package.

While writing a minimal R package is really pretty simple, R packages are still considered an advanced topic and rightly the subject of completely separate books. We recommend Hadley Wickham’s Writing R Packages which is available in press or online for more detailed reading. But our unit today is merely to give you a taste for creating an R package that passes “check” by creating the necessary DESCRIPTION file and adding roxygen documentation for our code.

Skim the readings on package DESCRIPTION metadata and object documentation as references for this exercise.
