## Installation

`$ npm i ml-rolling-ball-baseline`

## Usage

```js
import { rollingBall } from 'ml-rolling-ball-baseline';

// spectrum is an array
const spectrum=[1, 2, 1, ...];

// you need to provide and array with the data and
// two numbers indicating the "size" of the balls,
// i.e., the maximization/minimization and the smoothing window.
const baseline = rollingBall(spectrum, 200, 400);
```
