helper that loads multiple seasons from the data repo either into memory or writes it into a db using some forwarded arguments in the dots

load_wnba_pbp(seasons, ..., qs = FALSE)

Arguments

seasons

A vector of 4-digit years associated with given women's college basketball seasons.

...

Additional arguments passed to an underlying function that writes the season data into a database (used by update_wnba_db()).

qs

Whether to use the function qs::qdeserialize() for more efficient loading.

Value

A dataframe with 42 columns

shooting_play

Logical value (TRUE/FALSE) indicating whether the play was a shooting play

sequence_number

Sequence number is supposed to represent a shot-possession, examine the last two numbers to see if there are multiple events that occur within the same shot-possession. A shot-possession is basically any sequence of plays until there is a shot, change in possession, and probably things like technical fouls and the like. So as soon as a shot goes up, a new sequence starts regardless, even if the shooting team retains possession via offensive or deadball rebound. The first portion of the number is usually time related (i.e. the numeric representation of when the sequence started, from a seconds remaining in the period perspective or so)

period_display_value

Long form of period (1st quarter, 2nd Quarter, OT, etc.)

period_number

The numeric period of play in the game

home_score

Home score at the time of the play

coordinate_x

The entire scale is a rectangle of size 25x47, intended as a half-court representation of the basketball court (i.e. on the side of the offense), with each coordinate unit representing a foot. It appears that the basket is roughly represented as the (25, 0) point. This is a nonsensical definition when considering that the basket overhangs the court, with the backboard aligned 48 inches from the baseline, then the center of the hoop being roughly 11 inches from there. This is an idiosyncracy of either sensor placement or software and data entry. Use your best judgement in making your charts, I think you will find that making some translations will be helpful.
