change_pop_oldcc: change vector population based on old carrying capacity...

In AndySouth/resistanceGame: prototyping an insecticide resistance management computer game

Description

simple logistic model to change vector population based on growth rate, K, insecticide and resistance

Usage

change_pop_oldcc(pop, rate_growth, carry_cap, insecticide_kill, resist_freq,
  resistance_modifier, insecticide_on, resistance_on, randomness = 0,
  never_go_below = 0.01)

Arguments

pop	vector population in this timestep
rate_growth	population growth rate
carry_cap	carrying capacity (K) in the logistic model
insecticide_kill	kill rate due to insecticide
resist_freq	frequency of resistance
resistance_modifier	modifies effect of resistance
insecticide_on	whether insecticide is applied 0=no, 1=yes
resistance_on	whether there is resistance to the applied insecticide 0=no, 1=yes
randomness	0-1 0=none, 1=maximum
never_go_below	restock at this level if pop goes below it

Value

float population in next timestep

Examples

change_pop_oldcc(pop=0.5, rate_growth=0.4, carry_cap=1, insecticide_kill=0.4, resist_freq=0.2, resistance_modifier=1, resistance_on=1, insecticide_on=1)
