GeoTox open-source R software package for characterizing the risk of
perturbing molecular targets involved in adverse human health outcomes
based on exposure to spatially-referenced stressor mixtures via the
GeoTox framework - otherwise known as source-to-outcome-continuum
modeling. The package, methods, and case-studies are described in
Messier, Reif, and Marvel, 2024,
medRxiv-Preprint.
The GeoTox framework was first described in Eccles et al. A geospatial modeling approach to quantifying the risk of exposure to environmental chemical mixtures via a common molecular target. Sci Total Environ. 2023 Jan 10;855:158905.

pak::pak("NIEHS/GeoTox")Figure 1 below shows the steps in the source-to-outcome-continuum or
GeoTox modeling framework that is capable in the GeoTox package.
blue text nodes represent an object
and green text, rounded nodes
represent a methodology or function required to go from one to the next.
The GeoTox package uses R S3 object-oriented programming to create the
GeoTox object. The GeoTox object is a list that contains all of
the information required to run the analysis including tracking
exposure, assays, dose-response, and geospatial referencing.
