calculate_player_stats(pbp, weekly = FALSE)

Arguments

pbp

A Data frame of NFL play-by-play data typically loaded with load_pbp() or build_nflfastR_pbp(). If the data doesn't include the variable qb_epa, the function add_qb_epa() will be called to add it.

weekly

If TRUE, returns week-by-week stats, otherwise, stats for the entire Data frame.

player_id

ID of the player. Use this to join to other sources.

player_name

player_display_name

Full name of the player

position

Position of the player

position_group

Position group of the player

headshot_url

URL to a player headshot image

season_type

REG or POST if weekly is TRUE

opponent_team

The player's opponent team if weekly is TRUE

completions

dakota

Adjusted EPA + CPOE composite based on coefficients which best predict adjusted EPA/play in the following year.
