Overview

About

Maintained by Sadikul IslamCRAN page ↗

Provides a comprehensive, modular framework for computing the Soil Quality Index (SQI) using six established methods: Linear Scoring (Doran and Parkin, 1994, doi:10.2136/sssaspecpub35.c1), Regression-based (Masto et al., 2008, doi:10.1007/s10661-007-9697-z), Principal Component Analysis-based (Andrews et al., 2004, doi:10.2136/sssaj2004.1945), Fuzzy Logic, Entropy Weighting (Shannon, 1948, doi:10.1002/j.1538-7305.1948.tb01338.x), and TOPSIS (Hwang and Yoon, 1981, doi: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, doi:10.2136/sssaspecpub35.c4). Includes automated Minimum Data Set selection via Principal Component Analysis with Variance Inflation Factor filtering (Kaiser, 1960, doi:10.1177/001316446002000116), one-way ANOVA with Tukey HSD post-hoc tests, leave-one-out sensitivity analysis, and publication-quality visualization using 'ggplot2'.

Changes in 0.1.0

Initial Release

Added make_config() and validate_data() for data preparation.
Added four scoring functions: score_more(), score_less(), score_optimum(), score_trapezoid(), and score_custom().
Added score_all() dispatcher for batch variable scoring.
Added select_mds() for PCA-based Minimum Data Set selection with VIF filtering.
Added six SQI indexing methods: sqi_linear(), sqi_regression(), sqi_pca(), sqi_fuzzy(), sqi_entropy(), sqi_topsis().
Added sqi_compare() to run and tabulate all methods together.
Added sqi_anova() with Tukey HSD post-hoc test.
Added sqi_sensitivity() for leave-one-out sensitivity analysis.

Added six visualization functions: plot_scores(), plot_sqi(), plot_radar(), plot_pca_biplot(), plot_scoring_curves(), plot_sensitivity().
Added hypothetical soil_data dataset (100 observations, 14 variables, 5 land-use systems, 2 depths).

Install

R (CRAN)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("SQIpro", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-sqipro

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-SQIpro

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-SQIpro

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
