Ensemble Platform for Species Distribution Modeling
Functions for species distribution modeling, calibration and evaluation, ensemble of models, ensemble forecasting and visualization. The package permits to run consistently up to 10 single models on a presence/absences (resp presences/pseudo-absences) dataset and to combine them in ensemble models and ensemble projections. Some bench of other evaluation and visualization tools are also available within the package.
The Free Group
The free group in R; juxtaposition is represented by a
plus. Includes inversion, multiplication by a scalar,
group-theoretic power operation, and Tietze forms. To cite the
package in publications please use Hankin (2022)
Ecological Drift under the UNTB
Hubbell's Unified Neutral Theory of Biodiversity.
Multivariate Polynomials
Various utilities to manipulate multivariate polynomials. The package is almost completely superceded by the 'spray' and 'mvp' packages, which are much more efficient.
Electrical Properties of Resistor Networks
Electrical properties of resistor networks using matrix methods.
The Weyl Algebra
A suite of routines for Weyl algebras. Notation follows

How to Add Two R Tables
Methods to "add" two R tables; also an alternative
interpretation of named vectors as generalized R tables, so that
c(a=1,b=2,c=3) + c(b=3,a=-1) will return c(b=5,c=3). Uses
'disordR' discipline (Hankin, 2022,
Knot Diagrams using Bezier Curves
Makes visually pleasing diagrams of knot projections using optimized Bezier curves.
The Complex Multivariate Gaussian Distribution
Various utilities for the complex multivariate Gaussian distribution and complex Gaussian processes.
The Exterior Calculus
Provides functionality for working with tensors, alternating
forms, wedge products, Stokes's theorem, and related concepts
from the exterior calculus. Uses 'disordR' discipline
