Bat Species Interval Dataset

Description

Interval-valued data for 21 bat species described by 4 morphological measurements. Benchmark dataset for matrix visualization.

Usage

data(bats.int)

Format

A data frame with 21 observations and 9 columns (4 interval variables in _l/_u Min-Max pairs, plus a label):

• species: Bat species name (character).

• head_l, head_u: Head length range (mm).

• tail_l, tail_u: Tail length range (mm).

• height_l, height_u: Ear height range (cm).

• forearm_l, forearm_u: Forearm length range (mm).

Details

Used to demonstrate color coding schemes, the HCT-R2E seriation algorithm, and distance measure comparisons (Gowda-Diday, Hausdorff, City-Block, L1, L2, etc.) for interval data.
