Mask ranges based on expert 
    knowledge or remote sensing layers. These tools can 
    be combined to quantitatively and reproducibly 
    generate a new map or to update an existing map.
    Methods include expert opinion and data-driven 
    tools to generate thresholds for binary masks.

Mass measurement corrections and uncertainties using calibration
    data, as recommended by EURAMET's guideline No. 18 (2015) 
    ISBN:978-3-942992-40-4 . The package provides classes, functions, and 
    methods for storing information contained in calibration certificates
    and converting balance readings to both conventional mass and real mass.
    For the latter, the Magnitude of the Air Buoyancy Correction factor employs
    models (such as the CIMP-2007 formula revised by Picard, Davis, Gläser, and
    Fujii (2008) <doi:10.1088/0026-1394/45/2/004>) to estimate the local air
    density using measured environmental conditions.

Some enhancements, extensions and additions
    to the facilities of the recommended 'MASS' package 
    that are useful mainly for teaching purposes, with
    more convenient default settings and user interfaces.
    Key functions from 'MASS' are imported and re-exported
    to avoid masking conflicts.  In addition we provide
    some additional functions mainly used to illustrate
    coding paradigms and techniques, such as Gramm-Schmidt
    orthogonalisation and generalised eigenvalue problems.

Constructing matrices for quick prototyping can be a nuisance, 
    requiring the user to think about how to fill the matrix with values using 
    the matrix() function. The %<-% operator solves that issue by allowing the 
    user to construct matrices using code that shows the actual matrices.

Friendly implementation of the Mann-Whitney-Wilcoxon test for competitive gene set enrichment analysis.

Estimation equations are from a variety of sources and associated error estimation.
