Current Version

This is the R version of the 2020 edition of Sean Lahman's Baseball Database, http://www.seanlahman.com/baseball-archive/statistics/.

• A notable change is that the old Master table, has been renamed People in the Lahman Database. To avoid breaking old scripts or examples, the People table has been copied to Master. In the next annual release, it is very likely that Master will be removed.

• A collection of vignettes has been added, illustrating various data manipulation tasks and analyses to explore some baseball questions. Try: browseVignettes("Lahman")

• In addition, the documentation has been updated to use dplyr and tidyr tools for database manipulation and ggplot2 for plots.
