Provides a simple interface to pull County Health Rankings & Roadmaps (CHR&R) county-level health data and metadata directly from 'Zenodo' <doi:10.5281/zenodo.18157681>. 
  Users can retrieve data for CHR&R release years 2010 through 2025. 
  CHR&R data support research and decision-making to promote health equity 
  and policies that help all communities thrive.

Implements coupling coordination degree (CCD) models and supports metacoupling analysis following Tang et al. (2021) <doi:10.1016/j.scs.2021.103405>.

Solves optimal pairing and matching problems using linear assignment
    algorithms. Provides implementations of the Hungarian method (Kuhn 1955)
    <doi:10.1002/nav.3800020109>, Jonker-Volgenant shortest path algorithm
    (Jonker and Volgenant 1987) <doi:10.1007/BF02278710>, Auction algorithm
    (Bertsekas 1988) <doi:10.1007/BF02186476>, cost-scaling
    (Goldberg and Kennedy 1995) <doi:10.1007/BF01585996>, scaling algorithms
    (Gabow and Tarjan 1989) <doi:10.1137/0218069>, push-relabel (Goldberg and
    Tarjan 1988) <doi:10.1145/48014.61051>, and Sinkhorn entropy-regularized
    transport (Cuturi 2013) <doi:10.48550/arxiv.1306.0895>. Designed for
    matching plots, sites, samples, or any pairwise optimization problem.
    Supports rectangular matrices, forbidden assignments, data frame inputs,
    batch solving, k-best solutions, and pixel-level image morphing for
    visualization. Includes automatic preprocessing with variable health
    checks, multiple scaling methods (standardized, range, robust), greedy
    matching algorithms, and comprehensive balance diagnostics for assessing
    match quality using standardized differences and distribution comparisons.

Detects all R installations on the current machine and migrates
    installed R packages between them. Provides find_routes() to discover R
    versions, manifest() to scan package libraries in a child R process, inventory()
    to compare two libraries, and ship() to install packages into a target R
    version using 'pak'. Includes a Shiny dashboard (open_hub()) for interactive
    source-to-target migration.
