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

Description

computes global grid of abundance of occurrences at multiple scales

Usage

oceanAbundGrid(occurrences, lat_name = "decimalLatitude",
  long_name = "decimalLongitude", extent = "global", cell_size = 5,
  min_long = -180, max_long = 180, min_lat = -90, max_lat = 90)

Arguments

occurrences	dataset of occurrences downloaded from OBIS or GBIF
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
from	source data, it can be "OBIS" or"GBIF"
latitude_name	variable name indicating latitude in the occurrences dataset
longitude_name	variable name indicating longitude in the occurrences dataset
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
