Vignette introduction

Introduction

These vignettes serve a dual purpose:

  • to introduce users of the Lahman package to the breadth and depth of the data, and a range of analysis and statistical methods that can be undertaken using the data in the package,

  • to introduce users to the statistical software R, but particularly to the modern use in statistics and data science encapsulated in the tidyverse of R packages designed to facilitate data input and manipulation and graphics.

Vignettes completed to-date:

  1. Relationship Between Strikeouts and Home Runs -- This vignette looks at the relationship between rate of strikeouts and home runs from the year 1950+. This question was inspired by Marchi and Albert (2014), Analyzing Baseball Data in R.

  1. Run Scoring Trends -- Major League Baseball average per-game run scoring for each season since 1901.
  1. Team Payroll and the World Series -- This vignette examines whether there is a relationship between total team salaries (payroll) and World Series success.

Further reading

A number of books and on-line resources use the Lahman package as material for the examples. These include:

Max Marchi and Jim Albert (2014) Analyzing Baseball Data with R (CRC Press)

  • the book makes frequent reference to the raw Lahman database files in CSV form; the Lahman package was relatively recent when the book was published, and authors make a brief mention of the package.

  • the book makes extensive use of the package to explain "the empirical Bayesian approach to estimation, credible intervals, A/B testing, mixture models, and other methods, all through the example of baseball batting averages."
