wrc: Weighted Runs Created

In peterxeno/sabermetrics-package: Sabermetrics Functions for Baseball Analytics

Description

Weighted Runs Created is a statistic which attempts to credit a hitter for the value of each outcome.

Usage

wrc(wOBA, PA, year)

Arguments

wOBA	Weighted On Base Average
PA	Plate Appearances
year	Season

Details

wRC is reported with runs as the units

Value

Returns a value equal to (((wOBA-linearWeights$wOBA[which(linearWeights$Season == year)])/linearWeights$wOBAScale[which(linearWeights$Season == year)])+weights$RPerPA[which(linearWeights$Season == year)])*PA

Note

wRC is considered a better representation of offensive value than something like ops

Examples

## Let's calculate Mike Trout's 2014 wRC
## He had a wOBA of .402 and 705 PA's
## We should return 125.879
wrc(.402,705,2014)

## The function is currently defined as
function (wOBA, PA, year) 
{
    wrc <- (((wOBA - linearWeights$wOBA[which(linearWeights$Season == 
        year)])/linearWeights$wOBAScale[which(linearWeights$Season == 
        year)]) + weights$RPerPA[which(linearWeights$Season == 
        year)]) * PA
    return(wrc)
  }
