finch

Data for nine morphological traits for five species of Darwin's finches occurring on Isabela Island. Demonstration analysis of hypervolume overlaps between all pairs of species.

Estimates the shape and volume of high-dimensional datasets and performs set operations: intersection / overlap, union, unique components, inclusion test, and negative feature detection. Uses stochastic geometry approach to high-dimensional kernel density estimation. Builds n-dimensional convex hulls (polytopes). Can measure the n-dimensional ecological hypervolume and perform species distribution modeling.
