Description

creates a richness raster from multispecies occurrences data

Usage

oceanRichness(occurrences, species_name = "species",
  long_name = "decimalLongitude", lat_name = "decimalLatitude",
  extent = "global", min_long = -180, max_long = 180, min_lat = -90,
  max_lat = 90, cell_size = 5, richness_map = F)

Arguments

occurrences	species occurrences dataframe, with at least longitude and latitude columns
long_name	column name for longitudes in the "occurrences" dataframe
lat_name	column name for latitudes in the "occurrences" dataframe
min_long	minimum longitude of the analysis
max_long	maximum longitude of the analysis
max_lat	maximum latitude of the analysis
cell_size	interger indicating grid cell size
richness_map	plot the resulting richness map
species_names	column name for species names in the "occurrences" dataframe
max_long	minimum latitute of the analysis

Value

The result is an object of class raster with richness grid cell
