Description

Population Dynamics Model with Age Classes for an insect

Usage

population.age.model(rb = 3.5, mE = 0.017, rE = 0.172, m1 = 0.06,
  r12 = 0.217, m2 = 0.032, r23 = 0.313, m3 = 0.022, r34 = 0.222,
  m4 = 0.02, r4P = 0.135, mP = 0.02, rPA = 0.099, mA = 0.027,
  iA = 0, duration = 100, dt = 1)

iA	: input rate of adult (unit.day-1)
duration	: simulation duration
dt	: time step for integration

Value

data.frame with values for state variables for each time step.
