iris.int: Iris Species Interval Dataset

In dataSDA: Datasets and Basic Statistics for Symbolic Data Analysis

Iris Species Interval Dataset

Description

Interval-valued version of the classic iris dataset, aggregated from Fisher's iris data into 30 interval observations across 3 species (Setosa, Versicolor, Virginica). Each observation represents a group of flowers with ranges for sepal and petal measurements.

Usage

data(iris.int)

Format

A data frame with 30 observations and 5 variables:

• sepal_length: Sepal length range (cm).

• sepal_width: Sepal width range (cm).

• petal_length: Petal length range (cm).

• petal_width: Petal width range (cm).

• class: Species (Setosa, Versicolor, Virginica).
