Fig. 4From: specificity: an R package for analysis of feature specificity to environmental and higher dimensional variables, applied to microbiome species dataCount of bacterial and archaeal species that exhibited significant specificity to metabolomic composition in human gut microbiome data. Each bar represents the number of species (out of 201 total) that showed significant specificity to the composition of a given metabolomic class. Ordering of metabolomic classes on the horizontal axis is arbitraryBack to article page
