Adds a dispersal constrain to a scenario object.

Adds a dispersal constrain to a scenario object.

Usage

# S4 method for BiodiversityScenario,character,numeric
add_constraint_dispersal(mod,method,value)

Arguments

mod

A BiodiversityScenario object with specified predictors.

method

A character indicating the type of constraints to be added to the scenario. See details for more information.

value

For many dispersal "constrain" this is set as numeric value specifying a fixed constrain or constant in units "m" (Default: NULL). For kissmig the value needs to give the number of iteration steps (or within year migration steps). For adaptability constraints this parameter specifies the extent (in units of standard deviation) to which extrapolations should be performed.

type

A character indicating the type used in the method. See for instance `kissmig`.
