  n_years = 20,
  start_year = 2000,
  n_categories = 3,
  seed = 42L
)

Arguments

n_years: Integer. Number of consecutive years to simulate starting from start_year. Defaults to 20.
start_year: Integer. First calendar year in the sequence. Defaults to 2000.
n_categories: Integer. Number of distinct groups. Defaults to 3.
seed: Integer passed to set.seed for reproducibility. Defaults to 42.

Value
