Append Advanced Metrics to a Box Score

Detects the standard hoopR / stats.nba.com box-score columns present in df and appends the advanced metrics it can compute from them (true-shooting %, effective field-goal %, free-throw rate, turnover %, assist-to-turnover ratio and Hollinger game score). Columns are matched case-insensitively against common aliases; metrics whose inputs are absent are skipped (reported via a message), so it is safe to pass any box score.

Usage

nba_add_advanced_metrics(df)

Arguments

df

A data frame / tibble of player or team box-score rows.

Value

df with the available advanced-metric columns appended.
