Simulate population growth — bbr

This function uses the output of bbr_survival() and bbr_recruitment() to estimate population growth (\(\lambda\)) using the Hatter-Bergerud equation (Hatter and Bergerud, 1991). Monte Carlo simulation is used to generate confidence limits.

bbr_growth(survival, recruitment)

Arguments

survival: A data frame generated by bbr_survival().
recruitment: A data frame generated by bbr_recruitment().

Value

A data.frame.

Details

See the vignette("methods", package = "bbouretro") for descriptions of the equations used. The raw_values can be plotted using bbr_plot_growth_distributions() and the summary data frame can be output using bbr_growth_summarize() or plotted using bbr_plot_growth().
