Tests and assertions to perform frequent argument checks. A
    substantial part of the package was written in C to minimize any worries
    about execution time overhead.

Validates common string formats including financial
    identifiers (ISIN, CUSIP, SEDOL, FIGI, IBAN, LEI), publication
    identifiers (ISBN, ISSN, DOI, ORCID), and general formats (email,
    UUID, URL, semver), with check digit verification where applicable.

Provides a lightweight data validation and testing toolkit for R. 
    Its guiding philosophy is that adding code-based data checks to users' 
    existing workflow should be both quick and intuitive. The suite of 
    functions included therefore mirror the common data checks many users 
    already perform by hand or by eye. Additionally, the 'checkthat' package is 
    optimized to work within 'tidyverse' data manipulation pipelines.

Provides automated checks for common Comprehensive R Archive
    Network (CRAN) submission issues that are not caught by standard
    'R CMD check'. Consolidates ad-hoc requirements that CRAN reviewers
    enforce but standard checks do not surface, helping 'R' package
    maintainers identify and fix issues before submission to reduce
    rejection rates. Covers code-pattern issues, DESCRIPTION-field
    formatting, documentation problems, and general package structure
    concerns.

Provides a flexible, extendable representation of an ecological community and a range of functions for analysis and visualisation, focusing on food web, body mass and numerical abundance data. Allows inter-web comparisons such as examining changes in community structure over environmental, temporal or spatial gradients.

Given a non-linear model, calculate the local explanation. 
    We purpose view the data space, explanation 
    space, and model residuals as ensemble graphic interactive on a shiny 
    application. After an observation of interest is identified, the normalized 
    variable importance of the local explanation is used as a 1D projection
    basis. The support of the local explanation is then explored by changing
    the basis with the use of the radial tour <doi:10.32614/RJ-2020-027>;
