Details

Calculate Team-level Consistency

team_consistency(year=2015)

Calculate FIP and related metrics for any set of data

fips_plus(df)

Calculate wOBA and related metrics for any set of data

woba_plus(df)

Label Statcast data as imputed

statcast_df <- scrape_statcast_savant("2017-05-01", "2017-05-02")
  sc_df <- label_statcast_imputed_data(statcast_df)
  mean(sc_df$imputed)

Generate run expectancy and related measures from Baseball Savant data

df <- statcast_search(start_date = "2016-04-06", end_date = "2016-04-15", 
                   playerid = 621043, player_type = 'batter') 
  run_expectancy_code(df, level = "plate appearances")

Generate linear weight values for events using Baseball Savant data

df <- statcast_search(start_date = "2016-04-06", end_date = "2016-04-15", 
                   playerid = 621043, player_type = 'batter') 
  df <- run_expectancy_code(df, level = "plate appearances")
  linear_weights_savant(df, level = "plate appearance")
