The 2020 update that will be released as v8.x is currently under development. You can the following to load a pre-release (but potentially incomplete) version:

library(devtools)
dev_mode()
install_github("cdalzell/Lahman", ref="feature/2019-data-update")
#  ...test ...
dev_mode()  # revert to previous

This is the R version of the 2019 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 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.

For the current CRAN version, simply use:

install.packages("Lahman")

The current up to date pre-CRAN release version can be installed in your R library via:

library(devtools)
install_github("cdalzell/Lahman", ref="master")

If you wish to use a non-release version of Lahman, use dev_mode().

dev_mode()
install_github("cdalzell/Lahman", ref="insert_branch_name_here")
#  ...test ...
dev_mode()  # revert to previous

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