coo_eccentricity: Calculates the eccentricity of a shape

Description

coo_eccentricityeigen uses the ratio of the eigen values (inertia axes of coordinates). coo_eccentricityboundingbox uses the width/length ratio (see coo_lw).

Usage

coo_eccentricityeigen(coo)
# S3 method for default
coo_eccentricityeigen(coo)
# S3 method for Coo
coo_eccentricityeigen(coo)
coo_eccentricityboundingbox(coo)
# S3 method for default

a matrix of (x; y) coordinates or any Coo

Value

numeric for single shapes, list for Coo.
