lambda_invasion: Rate of migration followed by survival

In robjohnnoble/demonanalysis: Analysis and plotting of demon data

Description

Rate of migration followed by survival

Usage

lambda_invasion(i, K, m, r1, r2, migration_type = 0, death_rate = 1,
  d = NA)

Arguments

i	number of cells of the focus type
K	deme carrying capacity
m	migration rate per cell, relative to birth rate
r1	birth rate of cells in the destination deme, relative to reference birth rate
r2	birth rate of migrating cells, relative to r1
migration_type	0 or 1 (see details)
death_rate	death rate of migrating cells, relative to death rate of cells in destination deme
d	migration distance relative to 1/sqrt(K); if NA then d is set to sqrt(K)

Details

If migration_type = 0 (meaning that migration rate is correlated with birth rate) then the migration rate will be multiplied by a factor of r2 * r1. Otherwise no adjustment will be made.

Value

The rate of migration followed by survival, when $i$ cells are attempting to migrate.

Examples

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