mig_rate: Demon migration rate

In robjohnnoble/demonanalysis: Analysis and plotting of demon data

Description

Quadratic formula used to set migration rate in demon.cpp

Usage

mig_rate(K, migration_type = 0, migration_edge_only = 0,
  migration_rate_scales_with_K = 1)

Arguments

K	deme carrying capacity
migration_type	0, 1, 2 or 3 (see details)
migration_edge_only	whether migration occurs at the edge only
migration_rate_scales_with_K	whether to divide by sqrt(K)

Details

Meaning of migration_type:

• 0: migration, such that a migration attempt occurs only following a birth event

• 1: migration, such that migration is independent of birth

• 2: fission, such that a fission attempt occurs only following a birth event

• 3: fission, such that fission is independent of birth

Value

The dispersal speed.

Examples

mig_rate(32)
mig_rate(32, migration_type = 2)
