R/calc_population_growth.R
calc_population_growth.RdUpdates the species' population size. This change is a function of the number of individuals that grow out of their present size class and the number that remain.
calc_population_growth(nSize, nSpecies, N, probGrowOut)Number of size class intervals species can grow through
Number of species in the model
A matrix (nSize x nSpecies) of species abundance (number of individuals)
A matrix (nSize x nSpecies) of proportions.
Note: probGrowOut = 0 for size classes in which a species does not reach and probGrowOut = 0 for largest size class. It is not possible to grow out of the largest size class since it is determined by Linf. See calc_phi
