Clean Play by Play Data

Description

Clean Play by Play Data

Usage

clean_pbp(pbp, ...)

Arguments

pbp	is a Data frame of play-by-play data scraped using fast_scraper().
...	Additional arguments passed to a message function (for internal use).

Details

Build columns that capture what happens on all plays, including penalties, using string extraction from play description. Loosely based on Ben's nflfastR guide (https://www.nflfastr.com/articles/beginners_guide.html) but updated to work with the RS data, which has a different player format in the play description; e.g. 24-M.Lynch instead of M.Lynch. The function also standardizes team abbreviations so that, for example, the Chargers are always represented by 'LAC' regardless of which year it was. Starting in 2022, play-by-play data was missing gsis player IDs of rookies. This functions tries to fix as many as possible.
