run_integration: Run an integration over time

In boydorr/ProgInR: Reproducible Programming in R helper code

Description

A generic function to integrate a series of ODEs. Designed to have arguments compatible with other run_xxx() functions, rather than optimally designed for ode(). deriv_function must have three arguments (t, pop_vec, param_vec), where t is the time, pop_vec contains the current state of the population in a vector with named elements, and param_vec contains a vector of named parameters. It must return a list with two elements, the first of which is a vector of the derivatives of the population at pop_vec, and the second is an empty vector.

Usage

run_integration(
  deriv_function,
  populations,
  end.time,
  timestep = 1,
  debug = FALSE,
  ...
)

Arguments

deriv_function	Dunction to calculate derivative
populations	Data frame with columns corresponding to function requirements
end.time	End time of simulation
timestep	(optionally) record the state every timestep - default 1
debug	(optionally) Do you want to print out a limited amount of debugging information about your code? - default FALSE
...	Other arguments for deriv_function, mostly parameters

Value

Data frame containing population history of simulation over time
