Generate vector field for phase portrait of mutualism model

Used internally by plot_mutualism_portrait().

Usage

mutualism_vector_field(sim_df, vec.density = 20, vec.scale = 0.1)

Arguments

sim_df

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

vec.density

Density of vectors, specified as a single numeric value larger than 0. e.g. If vec.density = 20 (default), a 20 \(\times\) 20 point grid evenly spaced along each axis is generated, where each grid point is the starting point of a vector.

vec.scale

Value to scale magnitude of vectors by, specified as a single numeric value larger than 0. e.g. If vec.scale = 0.1 (default) the magnitude of each vector is 0.1 times the magnitude of the vector produced by running run_mutualism() for one time step given each starting point (specified via vec.density) and params (inherited from sim_df).

Value

A data frame of vector start and end point values, collectively representing the vector field for a phase portrait of the model of mutualism with saturating functional response.
