title: 'SQIpro: Comprehensive Soil Quality Index Computation and Visualization'
version: 0.1.0
doi: 10.32614/CRAN.package.SQIpro
abstract: 'Provides a comprehensive, modular framework for computing the Soil Quality
  Index (SQI) using six established methods: Linear Scoring (Doran and Parkin, 1994,
  <https://doi.org/10.2136/sssaspecpub35.c1>), Regression-based (Masto et al., 2008,
  <https://doi.org/10.1007/s10661-007-9697-z>), Principal Component Analysis-based
  (Andrews et al., 2004, <https://doi.org/10.2136/sssaj2004.1945>), Fuzzy Logic, Entropy
  Weighting (Shannon, 1948, <https://doi.org/10.1002/j.1538-7305.1948.tb01338.x>),
  and TOPSIS (Hwang and Yoon, 1981, <https://doi.org/10.1007/978-3-642-48318-9>).
  Implements four variable scoring functions: more-is-better, less-is-better, optimum-value,
  and trapezoidal, following Karlen and Stott (1994, <https://doi.org/10.2136/sssaspecpub35.c4>).
  Includes automated Minimum Data Set selection via Principal Component Analysis with
  Variance Inflation Factor filtering (Kaiser, 1960, <https://doi.org/10.1177/001316446002000116>),
  one-way ANOVA with Tukey HSD post-hoc tests, leave-one-out sensitivity analysis,
  and publication-quality visualization using ''ggplot2''.'
