The dragon (Deep time Redox Analysis of the Geobiology Ontology Network) package provides a Shiny Application for examining mineral-chemistry networks over deep time on Earth, with a specific application of investigating biologically-relevant evolution of element redox states. dragon uses igraph and visNetwork library (a terribly handy R wrapper for vis.js) to construct user-friendly interactive networks.
This package was written by Stephanie J. Spielman, Ph.D. at Rowan University for collaborative research with Eli K. Moore, Ph.D. at Rowan University and is lisenced under GPL-3.
