A small three-species mizerExtensionTemplate model built from a subset of
the North Sea species parameters bundled with mizer (Sprat, Herring, Cod).
It demonstrates all five extension mechanisms provided by this template
package: an extra encounter term, a seasonal encounter multiplier, an
allometric background mortality, a dynamical plankton component, and an
overridden getBiomass() generic.
Format
A mizerExtensionTemplate object (an S4 subclass of mizer::MizerParams) with 3 species and a plankton component.
Details
Because the object is stored in the package's data/ directory it is
lazy-loaded by R. The package's .onLoad hook replaces the plain binding
with an active binding so that every access to example_params calls
mizer::coerceToExtensionClass() and returns an object with the correct
S4 extension class for the extension chain that is currently registered in
the session.
See also
newExtensionTemplateParams() for the constructor used to build
this object, getBiomass.mizerExtensionTemplate() for the overridden
generic, mizerExtensionTemplate for the S4 class definition.
