generation_raster: Apply a 'demography' Object to a Raster

In petrelharp/landsim: Simulate Populations on Landscapes

Description

This steps a population, stored as a Raster*, forwards by one generation, according to the parameters in a demography object, (which can also be passed in separately; see demography).

Usage

generation_raster(population, demography, prob.seed = demography$prob.seed,
  fecundity = demography$fecundity,
  prob.germination = demography$prob.germination,
  prob.survival = demography$prob.survival,
  pollen.migration = demography$pollen.migration,
  seed.migration = demography$seed.migration,
  genotypes = demography$genotypes, mating = demography$mating, ...)

Arguments

population	A Raster* object.
demography	A demography object, containing the below parameters.
prob.seed	Probability of producing seed, per individual.
fecundity	Mean number of seeds produced, per individual, if seeds are produced.
prob.germination	Probability of germination (establishment) per seed.
prob.survival	Probability of survival per already-extant individual.
pollen.migration	A migration object for pollen dispersal.
seed.migration	A migration object for seed dispersal.
genotypes	A character vector of genotypes.
mating	An array giving probabilities for offspring genotypes given parental genotypes.
...	Additional parameters that will be passed to demographic functions.

Value

A new population of the same form as the old.
