What is the RANN package?

In this section, we’ll delve into the fundamental aspects and key features of the package.

The RANN package provides the functionality to compute the k nearest neighbors in a very efficient manner. It is used extensively in machine learning and data mining for tasks like clustering, outlier detection, and data cleaning.

Title: Fast Nearest Neighbour Search (Wraps ANN Library) Using L2 Metric
Description: 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. The distance is computed using the L2 (Euclidean) metric. Please see package 'RANN.L1' for the same functionality using the L1 (Manhattan, taxicab) metric.
Author: Sunil Arya and David Mount (for ANN), Samuel E. Kemp, Gregory Jefferis
Maintainer: Gregory Jefferis
