It leverages the network-like architecture of scientific models together with software quality metrics to identify chains of function calls that are more prone to generating and propagating errors. It operates on tbl_graph objects representing call dependencies between functions (callers and callees) and computes risk scores for individual functions and for paths (sequences of function calls) based on cyclomatic complexity, in-degree and betweenness centrality. The package supports variance-based uncertainty and sensitivity analyses after Puy et al. (2022) <doi:10.18637/jss.v102.i05> to assess how risk scores change under alternative risk definitions.

'SOHPIE' (pronounced as SOFIE) is a novel pseudo-value regression approach for differential co-abundance network analysis of microbiome data, which can include additional clinical covariate in the model. The full methodological details can be found in Ahn S and Datta S (2023) <arXiv:2303.13702v1>.

Sparsity Oriented Importance Learning (SOIL) provides a new variable importance measure for high dimensional linear regression and logistic regression from a sparse penalization perspective, by taking into account the variable selection uncertainty via the use of a sensible model weighting. The package is an implementation of Ye, C., Yang, Y., and Yang, Y. (2017+).

Soil health assessment builds information to improve decision in
    soil management. It facilitates assessment of soil conditions for crop suitability [such as those given by FAO
    <https://www.fao.org/land-water/databases-and-software/crop-information/en/>], 
    groundwater recharge, fertility, erosion, salinization [<doi:10.1002/ldr.4211>], 
    carbon sequestration, irrigation potential, and status of soil resources.

Facilitates basic and equation-based analyses of some important soil properties related to soil chemical environment and nutrient availability to plants.
