Root Exudate Feature Toolkit R package REFT version 0.1.4 Provides tools for molecule-oriented and reaction-centred analysis of root exudate datasets. It supports structural matching based on 'PubChem', calculation of molecular descriptors, and inference of candidate microbe-associated metabolic reactions using Kyoto Encyclopedia of Genes and Genomes ('KEGG') identifiers and Enzyme Commission ('EC') numbers. For background on these databases, see Kanehisa et al. (2023) <doi:10.1093/nar/gkac963> and Kim et al. (2023) <doi:10.1093/nar/gkac956>.
