Description

This dataset contains sonar signals bounced off a metal cylinder (mines) and a roughly cylindrical rock. The task is to classify whether the signal is from a mine or a rock based on the sonar signal patterns.

Usage

data(Sonar)

Format

A data frame with 208 rows and 61 columns representing different features of sonar signals.

• Attribute1: Continuous feature representing energy within a frequency band.

• Attribute2: Continuous feature representing energy within a frequency band.

• Attribute3: Continuous feature representing energy within a frequency band.

• ...: Additional continuous features (up to Attribute60).

• Class: Categorical target variable ('M' for mine, 'R' for rock).

Examples

# Load the dataset
data(Sonar)

# Print the first few rows of the dataset
