## Overview

{MetricsWeighted} provides weighted and unweighted versions of metrics and performance measures for machine learning.

## Installation

```r

# From CRAN

install.packages("MetricsWeighted")

# Development version

devtools::install_github("mayer79/MetricsWeighted")

```

## Usage

There are two ways to apply the package. We will go through them in the following examples. Please have a look at the vignette on CRAN for further information and examples. 

### Example 1: Standard interface

``` r

library(MetricsWeighted)

y <- 1:10

pred <- c(2:10, 14)

rmse(y, pred)            # 1.58

rmse(y, pred, w = 1:10)  # 1.93

r_squared(y, pred)       # 0.70

r_squared(y, pred, deviance_function = deviance_gamma)  # 0.78

```

### Example 2: data.frame interface

Useful, e.g., in a {dplyr} chain.

``` r

dat <- data.frame(y = y, pred = pred)

performance(dat, actual = "y", predicted = "pred")

> metric    value

>   rmse 1.581139

performance(

  dat, 

  actual = "y", 

  predicted = "pred", 

  metrics = list(rmse = rmse, `R-squared` = r_squared)

)

>    metric     value

>      rmse 1.5811388

> R-squared 0.6969697

```
