Description: Provides a robust set of tools for researchers and modelers to
    construct and define virtual ecological niches using ellipsoid geometries.
    It enables the identification and extraction of suitable environmental
    areas, simulation of species occurrence points with various sampling
    strategies, and visualization of niche boundaries and simulated occurrences
    in both environmental and geographic space. Inspired by methodologies in
    'NicheA' and the 'virtualspecies' R package, 'nicheR' aims to streamline
    the process of niche conceptualization and data generation for ecological
    studies. Methodological and theoretical foundations are described in
