Complex graphical representations of data are best explored using interactive elements.
  'parcats' adds interactive graphing capabilities to the 'easyalluvial' package.
  The 'plotly.js' parallel categories diagrams offer a good framework for
  creating interactive flow graphs that allow manual drag and drop sorting of dimensions
  and categories, highlighting single flows and displaying mouse over information. The
  'plotly.js' dependency is quite heavy and therefore is outsourced into a separate package.

An interactive 'shiny' application for Health Technology
    Assessment (HTA) parameter estimation. Converts between rates,
    probabilities, odds, and hazard ratios (HR); extrapolates survival
    curves (Exponential, Weibull, Log-Logistic); fits probabilistic
    sensitivity analysis (PSA) distributions (Beta, Gamma, LogNormal,
    Dirichlet) via the method of moments; calculates incremental
    cost-effectiveness ratios (ICERs), net monetary benefit (NMB),
    value-based pricing, and budget impact; adjusts costs for inflation,
    discounting, and purchasing power parity (PPP) across 30 countries;
    and adjusts background mortality using life-table methods. Designed
    for researchers building cost-effectiveness and budget-impact models
    who need auditable, formula-documented parameter transformations.
    Methods include Zhang and Yu (1998)
    <doi:10.1001/jama.280.19.1690> for odds ratio (OR) to relative
    risk (RR) conversion and Chinn (2000, Statistics in Medicine, 19,
    3127-3131) for effect-size transformations.

Construct parser combinator functions, higher order functions that
  parse input. Construction of such parsers is transparent and easy. Their main
  application is the parsing of structured text files like those generated by
  laboratory instruments. Based on a paper by Hutton (1992)
  <doi:10.1017/S0956796800000411>.

Provides fast, dependency-minimal tools to strip all cell formulas
    from standard Excel (.xlsx) files while preserving evaluated calculated
    values intact. It also supports exporting multi-sheet workbooks into
    standalone single-sheet files. By design, the package extracts only
    cell values and their formatting (styles) to ensure maximum speed and
    safety, discarding complex embedded objects such as images or charts.
