R4_data

A <code>2</code>-dimensional dataset from Wiroonsri and Preedasawakul (2023) generated from <code>5</code> different Gaussian distributions labeled as <code>1-5</code>.

datasets

Algorithms for checking the accuracy of a clustering result with known classes, computing cluster validity indices, and generating plots for comparing them.
The package is compatible with K-means, fuzzy C means, EM clustering, and hierarchical clustering (single, average, and complete linkage).
The details of the indices in this package can be found in:
