In cfbfastR: Access College Football Play by Play Data

Unnest ESPN CFB drive plays into a flat play-by-play table

Description

Turn a espn_cfb_game_drives() result carrying a plays list-column (produced with plays = "list") into the flat one-row-per-play table – every play in the full espn_cfb_game_pbp() schema with its drive-level columns carried alongside, prefixed drive_.

Usage

espn_cfb_unnest_plays(drives)

Arguments

drives

(data.frame required): a data frame produced by espn_cfb_game_drives(..., plays = "list") – i.e. carrying a plays list-column of full-schema play tibbles.

Details

Pure transform – no HTTP. espn_cfb_unnest_plays() unnests the plays list-column appended by espn_cfb_game_drives(..., plays = "list") and carries every drive-level column alongside each play, prefixed drive_ (e.g. drive_id, drive_result, drive_yards, drive_start_yard_line) so it never collides with the play's own columns. The result is identical in shape to espn_cfb_game_drives(..., plays = "expand") – the same flat table, one route via the plays argument, the other via this auxiliary function.

If drives does not carry a plays list-column the function aborts with a message telling the caller to run espn_cfb_game_drives(..., plays = "list") first.

Value

A data frame with one row per play:

col_name	types	description
drive_game_id	character	ESPN game identifier (drive-level column, drive_-prefixed).
drive_id	character	ESPN drive id the play belongs to (drive_-prefixed).
drive_result	character	Drive result code (drive_-prefixed; every drive-level column is carried with this prefix).
game_id	character	ESPN game identifier (play-level column).
play_id	character	ESPN play id.
...		Every remaining espn_cfb_game_pbp() play column, plus any optional participant columns present in the embedded tibbles.
