plot_odeweb function

Plot food web dynamics

Plot solution of the ODE for the food web. Currently only species and not nutrients are plotted.

plot_odeweb(x, nb_s)

Arguments

• x: matrix with solutions. First row should be the time vector.
• nb_s: numeric, number of species as in the model (e.g., create_model_Unscaled_nuts).

Returns

No return value, called for side effects.

Examples

## Not run:

library(ATNr)
library(deSolve)
set.seed(123)
# number of species, nutrients, and body masses
n_species <- 20
n_basal <- 5
n_nutrients <- 3
masses <- sort(10^runif(n_species, 2, 6)) #body mass of species
# create food web matrix
L <- create_Lmatrix(masses, n_basal)
L[, 1:n_basal] <- 0
fw <- L
fw[fw > 0] <- 1
model <- create_model_Unscaled_nuts(
  n_species,
  n_basal,
  n_nutrients,
  masses,
  fw
)
# initialize model as default in Schneider et al. (2016)
model <- initialise_default_Unscaled_nuts(model, L)
# defining integration time
times <- seq(0, 500, 5)
biomasses <- runif(n_species + n_nutrients, 2, 3)
sol <- lsoda_wrapper(times, biomasses, model, verbose = FALSE)
plot_odeweb(sol, model$nb_s)
