windDispGRASS: Dispersal of seeds by wind
In rkrug/seedDisp: Dispersal of seed routines

Description Usage Arguments Details Value Author(s)

Disperses seeds from a input raster layer in GRASS by using a 2 dimensional dispersal kernel matrix and stores the dispersed seeds in an output layer in RASS

1	windDispGRASS(SD2D, input, output="windDispSeeds", zeroToNULL = TRUE, overwrite=FALSE)

`SD2D`	Sedd Dispersal kernel 2D - `matrix` defining the 2D seed dispersal kernel
`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

This function is a wrapper around windDisp to facilitate the usage of GRASS as a backend. It retrieves the raster from GRASS and stores the resulting layer in GRASS again.

The MASK in GRASS is respected.

invisibly character name of the output layer
