Plot population trajectories over time for mutualism model

Generate a plot of trajectories of population sizes over time for the model of mutualism with saturating functional response.

Usage

plot_mutualism_time(sim_df)

Arguments

sim_df

Data frame of mutualism model simulation returned by run_mutualism().

Value

A ggplot object with trajectories of population sizes (N1, N2) plotted against time. Population carrying capacities for each species, calculated from model parameters, are also plotted.

Note

The plot generated with this function is constrained to display only the first quadrant (i.e. values of 0 and above) of the plane defined by N and time because negative values of N or time do not make biological sense. As a consequence, when sim_df is generated using negative values for r1 and/or r2, the corresponding lines for population carrying capacities will not be visible in the plot because they will lie beyond the plot's limits.
