Function to project SRKW population in the future using individual based models

Description

Function to project SRKW population in the future using individual based models

Usage

project(
  whale_data,
  seed = 123,
  n_years = 30,
  scenarios = c("1981:2020"),
  n_iter = 200,
  verbose = FALSE,
  p_female = NA,
  n_births = NA
)

Arguments

whale_data	the expanded data frame, returned by expand()
seed	the random seed used to initialize simulations, defaults to 123
n_years	the length of the time series projections, defaults to 30 time steps
scenarios	a character string, or vector of strings describing which scenario to be run. Should be entered as a range of years separated by a colon, e.g. "1981:1985" to use rates from 1981 to 1985 or ("1981:1985","1981:2021")
n_iter	the number of iterations per scenario, defaults to 200
verbose	whether to print status updates to screen, defaults to FALSE
p_female	The probability of a female birth, defaults to the empirical value since 1980
n_births	The number of births used to calculate p_female. By default, this defaults to the empirical value observed since 1980 the probability of female birth. Larger values result in more precise estimates of p_female
