data69_1: Waveform Dataset (UCI)

In classbound: Visualization for Classification Decision Boundaries

Waveform Dataset (UCI)

Description

A subset of the UCI Waveform Database Generator dataset (Version 1). Contains 5000 observations with 21 numeric features and a 3-class response variable. All 21 features contribute to class membership, making this a useful dataset for demonstrating high-dimensional boundary visualization, including 2D slice and projection-based approaches.

Usage

data(data69_1)

Format

A data frame with 5000 rows and 22 columns:

Y

Class label: a factor with 3 levels ("1", "2", "3")

Details

Each observation is generated from one of three waveform classes. All features are numeric; the response variable Y is a factor with levels "1", "2", and "3". Load the dataset with data(data69_1).

This dataset is included primarily to demonstrate high-dimensional boundary visualization with tools like PCA projection and tourr. For introductory 2D examples, the palmerpenguins::penguins dataset provides a more accessible alternative.
