do_four_factors_df_lineup: Four factors for lineups

Description

This function computes offense and defense four factors for a given lineup. The four factors are the effective field goal percentage (EFGP), the turnover percentage (TOVP), the offensive rebound percentage (ORBP) and the free throws rate (FTRate). They are well defined at http://www.rawbw.com/~deano/articles/20040601_roboscout.htm and https://www.basketball-reference.com/about/factors.html.

As a summary, EFGP is a measure of shooting efficiency; TOVP is the percentage of possessions where the team missed the ball; ORBP measures how many rebounds were offensive from the total of available rebounds, and FTRate is a measure of how often a team gets to the line.

Usage

do_four_factors_df_lineup(data_combs, team_name, type_lineup, type_period, type_opponent)

Value

A data frame with the four factors in defense and in offense for a given lineup.

Arguments

data_combs

type_lineup

Type of lineups to analyze. Options are 'quintet', 'quartet', 'trio', 'duo' and 'single'.

Details

Instead of defining the Offensive and Defensive Rebound Percentage as mentioned in the previous links, I have computed just the Offensive Rebound Percentage for the team and for its rivals. This makes easier to have four facets, one per factor, in the ggplot.
