In monteroserra/rOceansNew: Spatial Trends in Marine Biodiversity and Conservation

Description

computes global grid of abundance of occurrences at multiple scales

Usage

oceanDiversity(occurrences, species_name = "scientificName",
  lat_name = "decimalLatitude", long_name = "decimalLongitude",
  extent = "global", cell_size = 5, min_long = -180, max_long = 180,
  min_lat = -90, max_lat = 90, diversity_metric = "richness")

Arguments

occurrences	dataset of occurrences downloaded from OBIS or GBIF
lat_name	variable name indicating latitude in the occurrences dataset
long_name	variable name indicating longitude in the occurrences dataset
extent	spatial extent of the analysis:"global", "Mediterranean"
cell_size	size of the grid cells in degrees (?)
min_long	minimum longitude of the analysis
max_long	maximum longitude of the analysis
max_lat	maximum latitude of the analysis
diversity_metric	diversity metric to be computes: richness, shannon or simpson indeces
max_long	minimum latitute of the analysis

Details

The function creates downloads occurrences data from the specific sources and stores them in a data frame.

Value

The function returns a an object of class raster with abundance per cell
