A novel feature-wise normalization method based on a zero-inflated negative binomial model. This method assumes that the effects of sequencing depth vary for each taxon on their mean and also incorporates a rational link of zero probability and taxon dispersion as a function of sequencing depth.

Computation and visualization of Taxicab Correspondence Analysis, Choulakian (2006) <doi:10.1007/s11336-004-1231-4>.  Classical correspondence analysis (CA) is a statistical method to analyse 2-dimensional tables of positive numbers and is typically applied to contingency tables (Benzecri, J.-P. (1973). L'Analyse des Donnees. Volume II. L'Analyse des Correspondances. Paris, France: Dunod).  Classical CA is based on the Euclidean distance.  Taxicab CA is like classical CA but is based on the Taxicab or Manhattan distance.  For some tables, Taxicab CA gives more informative results than classical CA.

Interacts with a suite of web application programming interfaces
    (API) for taxonomic tasks, such as getting database specific taxonomic
    identifiers, verifying species names, getting taxonomic hierarchies, fetching
    downstream and upstream taxonomic names, getting taxonomic synonyms, converting
    scientific to common names and vice versa, and more. Some of the services
    supported include 'NCBI E-utilities' (<https://www.ncbi.nlm.nih.gov/books/NBK25501/>),
    'Encyclopedia of Life' (<https://eol.org/docs/what-is-eol/data-services>),
    'Global Biodiversity Information Facility' (<https://techdocs.gbif.org/en/openapi/>),
    and many more. Links to the API documentation for other supported services are
    available in the documentation for their respective functions in this package.

Download taxonomic databases, convert them into 'SQLite' format, 
    and query them locally for fast, reliable, and reproducible access to 
    taxonomic data.

Handling taxonomic lists through objects of class 'taxlist'.
    This package provides functions to import species lists from 'Turboveg'
    (<https://www.synbiosys.alterra.nl/turboveg/>) and the possibility to create
    backups from resulting R-objects.
    Also quick displays are implemented as summary-methods.
