BivalvePBDB | Occurrence data on bivalves from the Ypresian Data from the Paleobiology Database via the velociraptr package on May 17th, 2017
CellCount | Calculates degree x degree cell counts of a specified size
CHullArea | Performs Convex Hull area calculation
CHullAreaEarth | Performs convex hull area calculation from coordinate sets on the Earth's surface
CoordCollapse | Removes duplicate geographic locations and binds coordinates into a single element
CoordList_PBDB | Creates an occurrence matrix of taxa by coordinates from the Paleobiology Database
deg2rad | Converts degrees to radians
EqualAreaRectangle | Create a rectangular shaped distribution with equal area to a given area
GCD | Calculates the maximum pairwise great circle distance from a set of decimal degree coordinates
gcd_hf | Calculates the geodesic distance between two points specified by latitude and longitude using the Haversine formula
gcd_vif | Calculates the geodesic distance between two points specified by latitude/longitude using Vincenty inverse formula for ellipsoids
GeoCor | Function to calculate the correlation coefficient for pairwise comparisons between geographic range measures
GeoPerformance_SkewCV | Function to calculate the skewness and coefficient of variance for a set of geographic range calculations
GeoRange_MultiTaxa | Function to tabulate number of occurrences/locations, six geographic range measures, minimum and maximum latitude and longitude for each taxon in a dataset
