RangeFinder: Calculate range sizes of species and generates a histogram.

In LewisAJones/LBGSim: Latitudinal biodiversity gradient simulator

Description

Calculate range sizes of species and generates a histogram.

Usage

RangeFinder(
  data,
  metric = "latitude",
  breaks,
  write = FALSE,
  name = "simulation"
)

Arguments

data	Data.frame (colnames:x,y). A dataframe of species occurrences (species,x,y).
metric	Character. Which metric to use to calculate range: "latitude", "longitude" or "GCD" (Great Circle distance; WGS84 ellipsoid).
breaks	Integer. Number of breaks desired in plot. Value should relate to unit of measurement (e.g. in degree for latitude/longitude, km for GCD)

Value

A dataframe of the latitudinal (degrees), longitudinal (degrees), or Great Circle distance (kilometres) range of each species.
