Multidimensional unfolding using Schoenemann's algorithm for metric
   and Procrustes rotation of unfolding results.

Provides easy access to, and manipulation of, the Munsell 
    colours. Provides a mapping between Munsell's 
    original notation (e.g. "5R 5/10") and hexadecimal strings suitable 
    for use directly in R graphics. Also provides utilities 
    to explore slices through the Munsell colour tree, to transform 
    Munsell colours and display colour palettes.

Methods for interpolating data in the Munsell color system following the ASTM D-1535 standard. Hues and chromas with decimal values can be interpolated and converted to/from the Munsell color system and CIE xyY, CIE XYZ, CIE Lab, CIE Luv, or RGB.  Includes ISCC-NBS color block lookup.  Based on the work by Paul Centore, "The Munsell and Kubelka-Munk Toolbox".

Implementation of custom 'tidymodels' metrics for multi-class
    prediction models with a single negative class. Currently are implemented
    macro-average sensitivity and specificity as in Mortaz, Ebrahim (2020)
    "Imbalance accuracy metric for model selection in multi-class imbalance
    classification problems” <doi:10.1016/j.knosys.2020.106490> and a
    generalized weighted Youden index as in Li, D.L., Shen F., Yin Y., Peng
    J.X and Chen P.Y. (2013) “Weighted Youden index and its
    two-independent-sample comparison based on weighted sensitivity and
    specificity” <doi:10.3760/cma.j.issn.0366-6999.20123102>.

A graphical user interface tool to estimate ploidy from DNA cells stained with fluorescent dyes and analyzed by flow cytometry, following the methodology of Gómez-Muñoz and Fischer (2024) <doi:10.1101/2024.01.24.577056>. Features include multiple file uploading and configuration, peak fluorescence intensity detection, histogram visualizations, peak error curation, ploidy and genome size calculations, and easy results export.

Provides mailmerge methods for reading spreadsheets of addresses and other relevant information to create standardized but customizable letters.  Provides a method for mapping US ZIP codes, including those of letter recipients.  Provides a method for parsing and processing html code from online job postings of the American Political Science Association.
