dm.addSymmetricMigration: Adds symmetric migration between all populations

Description

This adds migration between all subpopulation, all with the same rate. Please look at the documentation for dm.addMigration for detailed information about migration.

Usage

dm.addSymmetricMigration(dm, lower.range, upper.range, fixed.value,
  par.new = T, new.par.name = "M", parameter, time.start = "0")

Arguments

dm

The demographic model to which migration events should be added.

par.new

If 'TRUE' a new parameter will be created using the arguments 'lower.range' and 'upper.range' or 'fixed.value'. It will be named 'new.par.name'. If 'FALSE' the argument 'parameter' will be evaluated instead.

lower.range

If you want to estimate the migration parameter (see note

upper.range

Same as lower.range, but the largest possible value.

fixed.value

If specified, the migration rate will not be estimated, but assumed to have the given value.

new.par.name

The name for the new parameter.

parameter

Instead of creating a new parameter, you can also set the mutation rate to an expression based on existing parameters. For example setting this to "M" will use an parameter with name M that you have previously created. You can also use R expression here,

time.start

The time point at which the migration with this rate starts.

Value

• The demographic model with migration

Examples

dm <- dm.createThetaTauModel(c(25,25), 100)
dm <- dm.addSymmetricMigration(dm, 0.01, 5, time.start="0.5*tau")
