change_pop: change vector population based on emergence

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

Description

simple simulation of vector population based upon emergence suggested by Nakul Chitnis

Usage

change_pop(pop, survival, emergence, insecticide_kill = 0.5,
  resist_freq = 0, resistance_modifier = 1, resist_intensity = 10,
  insecticide_on = 0, resistance_on = 0, randomness = 0,
  verbose = FALSE)

Arguments

pop	vector population in this timestep
survival	adult survival rate
emergence	emerging adults, can be a vector can be greater than 1
insecticide_kill	kill rate due to insecticide
resist_freq	ferquency of resistance
resistance_modifier	modifies effect of resistance (unlikely to be used in game)
resist_intensity	intensity of resistance 1,2,5 & 10 fold
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
verbose	whether to output diagnostics to console

Value

float population in next timestep

Examples

change_pop(pop=0.5, survival=0.4, emergence=1, insecticide_kill=0.4, resist_freq=0.2, resistance_modifier=1, resistance_on=1, insecticide_on=1, verbose=TRUE)
change_pop(pop=0.5, survival=0.7, emergence=0.3, insecticide_kill=0.4, resistance_on=0, insecticide_on=1, verbose=TRUE)
