# fp: Fielding Percentage In Sabermetrics: Sabermetrics Functions for Baseball Analytics

## Description

A measure that reflects the percentage of times a player successfully handles a batted or thrown ball.

## Usage

 `1` ```fp(po, a, e) ```

## Arguments

 `po` Putouts `a` Assists `e` Errors

## Details

Fielding percentage is not a particularly sought after defensive metric, especially with the advent of more comprehensive metrics such as UZR and DRS.

## Value

Returns a value equal to (po+a)/(po+a+e)

## Note

Fielding percentage is misleading in the fact that it does not account for a player's range – that is, if a player that cannot get to a ball gives up a hit instead of having an opportunity to make an out or error.

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11``` ```## Let's calculate Mike Trout's fielding percentage for 2014 ## He had PO = 383, A = 4, E = 3 ## We should get an output of .992 fp(383,4,3) ## The function is currently defined as function (po, a, e) { fp <- (po + a)/(po + a + e) return(fp) } ```
