targets: Number of pass plays where the player was targeted as a receiver
receptions: Number of pass receptions. Lateral receptions don't count as a reception

tgt_pct: Share of targets percentage
air_yards_share: Share of receiving_air_yards of the player to all team air_yards
wopr: Weighted Opportunity Rating. WOPR = 1.5 x target_share + 0.7 x air_yards_share
carries: Number of rush attempts including scrambles and kneel downs. Rushes after a lateral reception don't count as a carry
rushing_yards: Yards gained when rushing including scrambles and kneel downs. Also includes yards gained after obtaining a lateral on a play that started with a rushing attempt

passing_2pt_conversions: Two-point conversion passes
pacr: Passing Air Conversion Ratio. PACR = passing_yards / passing_air_yards
dakota: Adjusted EPA + CPOE composite based on coefficients which best predicts adjusted EPA/play in the following year

Arguments

pbp_db_tbl: Play-by-Play database table name (optional)
seasons: NFL season(s) (required) to obtain play-by-play data. The season can be defined as a single season, season = 2024. For multiple seasons, use either season = c(2023,2024)
week_min: Minimum week (required) to define whether pulling a range of weeks or the entire season. Use week_min = 1 for the first week of the season, must be an integer.
week_max: Maximum week (optional) to define a range of weeks to pull from an NFL season. If not defined, the data will be pulled for all weeks, beginning with week_min.
pbp_dp: Play-by-Play database path (optional)

Value

Dataframe with WR stats for user-defined season(s) and week(s) obtained from NFL play-by-play data

Details

The function get_wr_pbp_stats can be utilized to obtain player stats for a specified time frame that can include multiple seasons or even a range of weeks instead of the entire season. This includes stats for passing, rushing, and receiving obtained by using the nflfastR function calculate_player_stats(). The player stats are utilized to calculate fantasy points based on common scoring formats (4/6 point TD, STD, Half PPR, Full PPR). The function acquires stats by using cumulative play-by-play data by either loading from a saved database or using nflreadr::load_pbp(). The data is obtained for a user-defined season or multiple seasons. A range of weeks can also be defined with week_min and week_max. If the entire season is desired, use week_min = 1 and week_max does not need to be defined. To specify loading from a database, define the path to the database with pbp_db as well as the name of the table to load with pbp_db_tbl. To load from a database, you will need to save play-by-play data to a database using the nflfastR function, update_db(). For example, the database is saved by default as pbp_db with a table that is stored containing all play-by-play information called nflfastR_pbp. Assume that the database is saved in project_name/data/. Using the default naming scheme, nuclearff::get_pbp_data can be defined using the database with pbp_db = "data/pbp_db" and pbp_db_tbl = "nflfastR_pbp". Note that these two arguments must be defined as strings. For more information on calculated player stats, refer to the nflfastR calculate_player_stats()
