Description

assessment_coccurrences() accepts a list of species inventories downloaded from universalfqa.org and returns a complete listing of all co-occurrences. Repeated co-occurrences across multiple assessments are included, but self co-occurrences are not, allowing for meaningful summary statistics to be computed.
