birdDispGRASS: Dispersal of seeds by birds

In rkrug/seedDisp: Dispersal of seed routines

Description

Seed dispersal by birds from a seed layer using GRASS

Usage

birdDispGRASS(input, output, zeroToNULL, overwrite)

Arguments

input	name of GRASS raster layer specifying number of seeds to be dispersed - character
output	name of GRASS raster layer generated, containing the dispersed seeds - character
zeroToNULL	boolean if TRUE replace 0 with NA in the returned matrix, otherwise all NA will be replaced with 0
overwrite	boolean if TRUE, output will be overwritten if it exists

Details

This is a "dumb" implementation of sedd dispersal by birds, simply randomly distributing all seeds in the output raster.

The resulting seed layer is saved and, if it exists and overwrite==TRUE, overwritten.

The MASK in GRASS is respected.
