Spider: SPecies IDentity and Evolution in R, is an R package implementing a number of useful analyses for DNA barcoding studies and associated research into species delimitation and speciation. Included are functions for generating summary statistics from DNA barcode data, assessing specimen identification efficacy, and for testing and optimising divergence threshold limits. In terms of investigating evolutionary and taxonomic questions, techniques for sliding window, population aggregate, and nucleotide diagnostic analyses are also provided.
