Current Version

This is the R version of the 2021 edition of Sean Lahman's Baseball Database, https://www.seanlahman.com/baseball-archive/statistics/.

  • It now fully reflects the reorganization of data tables in Lahman's source, the most notable was the renaming of the old Master table, to People in the Lahman Database.

The current database schema is shown in the figure below:

  • 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.

Installation

For the current CRAN version, simply use:

install.packages("Lahman")

install_github("cdalzell/Lahman", ref="insert_branch_name_here")

Please report any problems or issues with this new version as an issue on this site.
