trophic_dynamics: Create a trophic_dynamics object to use in a trophic...

In jdyen/trophic: Trophic Models of Energetics to Estimate Carrying Capacity

Description

A 'trophic dynamics' object stores the trophic dynamics of a set of potentially interacting species.

Usage

build_trophic_dynamics(food_web, efficiency_matrix = NULL,
  dominance_matrix = NULL, ...)

is.trophic_dynamics(x)

## S3 method for class 'trophic_dynamics'
print(x, ...)

## S3 method for class 'trophic_dynamics'
plot(x, ...)

Arguments

food_web	a food_web object identifying (weighted) trophic links between species pairs
efficiency_matrix	an efficiency_matrix object storing the efficiency of energy conversion between all pairs of species
dominance_matrix	a dominance_matrix object identifying the relative dominance of a species over other species feeding off the same resource
...	further arguments passed to or from other methods
x	an object to print or test as a trophic_dynamics object

Value

An object of class trophic_dynamics

Examples

library(trophic)

# Construct the component objects
test_fw <- build_food_web(interaction_matrix = food_web)
test_efficiency_matrix <- build_efficiency_matrix(efficiency_mean = efficiency_mean,
                                                  efficiency_sd = 0.01)
test_dominance <- build_dominance_matrix(dominance = dominance_matrix)

# Construct the trophic_dynamics object
test_trophic_dynamics <- build_trophic_dynamics(food_web = test_fw,
                                                efficiency_matrix = test_efficiency_matrix,
                                                dominance_matrix = test_dominance)

# Construct a trophic_dynamics object with two food webs
test_trophic_dynamics <- build_trophic_dynamics(food_web = list(test_fw, test_fw),
                                                efficiency_matrix = test_efficiency_matrix,
                                                dominance_matrix = test_dominance)
