  "Description": "Provides a set of functions useful when evaluating the\nresults of presence-absence models. Package includes functions\nfor calculating threshold dependent measures such as confusion\nmatrices, pcc, sensitivity, specificity, and Kappa, and\nproduces plots of each measure as the threshold is varied. It\nwill calculate optimal threshold choice according to a choice\nof optimization criteria. It also includes functions to plot\nthe threshold independent ROC curves along with the associated\nAUC (area under the curve).",
