Project 3 Final Deliverable

The deliverable for this project is a fully developed R package, which contains functions to automate and streamline the data collection and analysis that you did in Units 1 and 2.

Along the way you will learn how to:

Final Deliverable

The package you create must have the following elements:

Structure

  • Package installs without errors or warnings using remotes::install_github("your-repo/your-package-name")
  • All functions are fully documented in the roxygen2 style.
  • All functions have at least one associated unit test in the testthat format.

Function Design

  • Package includes underlying helper functions that support primary functions.
  • Functions perform efficiently on moderately large data
  • At least one function uses data.table, arrow, and/or parallelization.

Content

Package must contain at least… - one data gathering function - one data cleaning/wrangling function - two data summarizing functions - two plotting functions - one statistical analysis function - one vignette describing package use

Stat 541 requirements

Stat 541 packages must also… - contain at least one function that uses tidy eval - pass all CRAN checks - have at least 80% test coverage as measured by covr - include at least one speed and memory benchmarking test in a vignette

Peer Review

In Week 9 your group will give (and receive) feedback to another group on their preliminary package setup. Your goal is to test the user-friendliness of the functions and to find places where the functions break.

Submission

You are required to submit both the link to your GitHub repository for your package, which should be fully installable from the link, and a .zip folder of your package.
