Create individual seabirds for the simulation
set_initialbirdtype.RdThis function creates a tibble holding one row per individual seabird. The values stored in this tibble do not change through the simulation, they describe characteristics that remain constant like species, sex and home colony.
Arguments
- seed
The seed used to ensure results are reproducible.
- Colonies
A tibble containing information about the colonies of interest in this simulation. Requires "code" with the colony codes and "ObsNpairs"
- thisSpecies
The two-letter code identifying the species of interest (only works with one species in v2.0.0).
- Pwfde
The probability of displacement across the population if encountering an ORD,where 0 means no displacement.
- Pwfbe
The probability across the population of experiencing a barrier effect when encountering an ORD. Only applies to birds who are displacement susceptible.
Examples
set_initialbirdtype(231, tibble::tibble(code="UK9004171", ObsNpairs=100), "Kw", 0.3, 1.0)
