similarityToolOff: Offensive Similarity Tool

In Metlover/similarityTool: Using Fangraphs Data, Generates Similarity Scores for Batters

Description

Finds the most similar players to a given player in a dataset based upon offensive peripheral data

Usage

similarityToolOff(battedBallVals, playerName, numResults = 10, year=2017)

Arguments

battedBallVals	A dataframe of offensive peripheral data from FanGraphs.
playerName	A string with the name of a player in the format "Firstname Lastname"
numResults	An integer. Defaults to 10.
year	An integer. Defaults to 2017.

Details

BattedBallVals are designed to be from FanGraphs, using the Batted Ball tab in conjunction with BB% and K%. To generate an appropriate dataset, use the "Custom Report" feature from FanGraphs. Each dataset must contain all of the following attributes (other values can be included, but will not be used): GB%, LD%, FB%, HR/FB, Pull%, Cent%, Oppo%, Soft%, Med%, Hard%, K%, BB% Name. The player name must be exactly formatted as it appears in FanGraphs.

Value

A dataframe with the players most similar to playerName and their similarity scores.

Note

Similarity scores will differ depending upon the sample size presented due to the normalization applied in the creation of the scores.
