Finds the k nearest neighbours for every point in a given dataset

in O(N log N) time using Arya and Mount's ANN library (v1.1.3). There is

support for approximate as well as exact searches, fixed radius searches

and bd as well as kd trees.

This package implements nearest neighbors for the Euclidean (L2) metric.

For the Manhattan (L1) metric, install the [RANN1](https://github.com/jefferislab/RANN/tree/master-L1) package.

For further details on the underlying ANN library, see https://www.cs.umd.edu/~mount/ANN.

## Installation

### Released versions

The recommendation is to install the released version from [CRAN](https://cran.r-project.org/) by doing:

```r

install.packages("RANN")

```

### Bleeding Edge

You can, however, use the **remotes** package to install the development version:

```r

# install.packages("remotes")

remotes::install_github("jefferis/RANN")

```
