Simulate growth of a (st)age-structured population

Simulate growth of a (st)age-structured population

Usage

run_structured_population_simulation(
  leslie_mat = matrix(c(0, 8, 1, 1, 0.4, 0, 0, 0, 0, 0.8, 0, 0, 0, 0, 0.1, 0), ncol = 4,
    byrow = TRUE),
  init = c(10, 10, 10, 10),
  time = 100
)

Arguments

leslie_mat

A leslie matrix

init

A vector of initial abundances in each (st)age

time

Length of time over which to run the simulation

Value

Returns a matrix with nrow = nrow(leslie_mat) and ncol = time

See also

plot_structured_population_size(), plot_structured_population_agedist(), and plot_structured_population_lambda() for plotting different aspects of the population trajectory, and plot_leslie_diagram() for plotting an transition diagram based on the specified Leslie matrix

ncol = 4, byrow = TRUE)
structured_pop_init <- c(10,10,10,10)
structured_pop_time <- 5

structured_pop_init, time = structured_pop_time)
