add.Data.to.Grid: Add Data to Grid

Description

This function adds the species occurence data to the grid.

Usage

add.Data.to.Grid(dataset.one.species, dimension, shift, resolution=1)

Arguments

dataset.one.species

A dataset containing one species with its ID (named: speciesID) and the longitude (named: long) and latitude (named: lat) of the occurence locations of that species.

dimension

The dimension of the processed grid.

shift

The geographic coordinates of the origin of the grid.

resolution

The resolution of the grid in (geographical) degree.

Value

• This function returns a grid which contains the species occurence information.

Details

This routine adds the species occurence data to the grid through adding their location as a point into it.

Examples

##load data
data(dataset.all.species)

##create grid parameters
dimension <- getDimension(dataset.all.species, resolution=1)
shift <- getShift(dataset.all.species)

#extract datasets of one species out of database
dataset.one.species <- extract.species(dataset.all.species, 3)

##add species occurence information to grid
grid <- add.Data.to.Grid(dataset.one.species, dimension, shift, resolution=1)
