seedProdBasicGRASS: basic seed production based on age

In rkrug/seedProd: Seep Production Routines

Description

Calculating seed production based on provided function

Usage

  seedProdBasicGRASS(age, inds, output,
    seedProdPerIndFunction, initial=FALSE, overwrite=FALSE)

Arguments

age	raster layer containing the age of the species in each cell
inds	raster layer containing the number of individuals per cell
output	name of the output raster layer which will containing the number of newly produced seeds
seedProdPerIndFunction	function used to calculate the number of seeds based on the age in each cell
initial	logical specifying if the seed production is initial, i.e. accumulative over their life time
overwrite	logical if TRUE, output will be overwritten if it exists

Details

Calculate seed production per cell based on the age and number of individuals per cell by using a user specified R function. Input and output is from GRASS raster layers.

If initial == TRUE, the seed production over the lifetime of the plant will be returned.

The function seedProdPerInd has to have the following form:

seedProdPerInd <- function(age){...}

where

age is the age of the plant and the function returns the nomber of seeds produced.

The MASK in GRASS is not respected.

Value

invisibly returns name of output layer
