Package Exports

w-cluster
w-cluster/dist/w-cluster.umd.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (w-cluster) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

w-cluster

A tool for data PCA(Principle Component Analysis) and cluster(K-Means & K-Medoids).

Documentation

To view documentation or get support, visit docs.

Installation

Using npm(ES6 module):

Note: w-cluster is mainly dependent on ml-pca, ml-kmeans and k-medoids.

npm i w-cluster

Example for PCA(Principle Component Analysis):
