disp_rate_min: Minimum limit on dispersal speed for migration model

In robjohnnoble/demonanalysis: Analysis and plotting of demon data

Description

Minimum limit on dispersal speed for migration model

Usage

disp_rate_min(r1, r2, K, m, migration_type = 0, symmetric = FALSE,
  two_dim = TRUE, d = NA)

Arguments

r1	birth rate of cells in the destination deme, relative to reference birth rate
r2	birth rate of migrating cells, relative to r1
K	deme carrying capacity
m	migration rate per cell, relative to birth rate
migration_type	0 or 1 (see details)
symmetric	whether migration occurs in both directions
two_dim	whether to adjust for two-dimensional growth
d	migration distance relative to 1/sqrt(K); if NA then d is set to sqrt(K)

Details

Assumes that a cell type cannot attempt to migrate until it reaches fixation.

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

Value

The lower limit on the growth rate of the radius, measured in cells (not demes).

Examples

disp_rate_min(1, 1.1, 2, 0.1, 0)
disp_rate_min(1, 1.1, 2, 0.1, 1)
