occs2sparse: Converts occurrence data into a sparse matrix object

Description

occs2sparse: Converts occurrence data into a sparse matrix object

Usage

occs2sparse(modelsparse, occs)

Arguments

modelsparse	A setA object returned by the function model2sparse
occs	A matrix or a data.frame containing two columns. The first one is the longitude and the second is the latitude.

Value

A sparse vector of zeros and ones.
