Create a new multi-resource, multi-species model

Create a new multi-resource, multi-species model

Usage

newMRParams(
  species_params,
  interaction = NULL,
  resource_params,
  resource_interaction = NULL,
  gear_params = data.frame(),
  no_w = 100,
  min_w = 0.001,
  max_w = NA,
  second_order_w = FALSE
)

Arguments

species_params

A data frame with the species parameters, with one row for each species.

interaction

Optional interaction matrix between species (predator species x prey species). Entries should be numbers between 0 and 1. By default all entries are 1.

resource_params

A data frame with the resource parameters

resource_interaction

Optional interaction matrix between species and resources (predator species x prey resource). By default all entries are 1.

gear_params

A data frame with the gear parameters, with one row for each gear-species pair.

no_w

The number of size bins in the consumer spectrum.

min_w

Sets the size of the eggs of all species for which this is not given in the w_min column of the species_params dataframe.

max_w

The largest size of the consumer spectrum. By default this is set to the largest w_max specified in the species_params` data frame.

second_order_w

Selects the second-order numerical scheme for the new model, passed through to mizer::newMultispeciesParams(). When second-order bin-averaging is switched on, the multiple-resource capacities, rates and initial abundances are built from the exact bin averages of their power laws rather than point-sampled at the left bin edge. Defaults to FALSE.

Value

An object of class MizerMRParams
