Equine Death and Breakdown in New York State

Reproducible Research Project Using R & R Markdown

Nick Hepler, University at Albany, College of Engineering and Applied Sciences

Objectives

This project examines summary statistics concerning Equine Death and Breakdown data obtained from the New York State Gaming Commission. The data contains information on every horse that has broken down, died, sustained a serious injury, or been involved in an incident at a track in New York State since 2009.

The objective of the author was to utilize the R language and environment for statistical computing and graphics to create a reproducible research project. The project employed Hadley Wickham's tidyverse collection of R packages and principles as outlined in the R for Data Science book. The project performs the following steps with the data:

1. Import
2. Tidy
3. Tranform
4. Visualize

The final report was written using R Markdown from RStudio.

Results Reproduction

The intention of this research project is to be reproducible. Reproducible research is the idea that data analyses, and more generally, scientific claims, are published with their data and software code so that others may verify and building upon the findings.

Source the download_data.R file in one of the following manners:
