R Code to support analysis linking taxonomic, occurrence, genetic, and conservation dimensions of marine animal diversity. This code reproduces figures and analyses fromWebb & Vanhoorne Linking dimensions of data on global marine animal diversity, Phil Trans R Soc B, doi: 10.1098/rstb.2019.0445, to quantify and visualise the availability of data on geographic occurrences, genetic sequences, conservation assessments, and DNA barcodes across all phyla and broad functional groups for >200,000 marine animal species.
