random_dates: Get random dates for graph nodes

In uqrmaie1/admixtools: Inferring demographic history from genetic data

Get random dates for graph nodes

Description

This function assigns a date (in generations) to each node in an admixture graph and is used in random_sim. The dates are drawn from a uniform distribution with given lower and upper bounds, unless the fix_leaf option is set to TRUE, in which case the dates of all leaf nodes returned by get_leafnames will be set to 0.

Usage

random_dates(graph, min = 1000, max = 1000, fix_leaf = FALSE)

Arguments

graph	An admixture graph
min	A lower limit of uniform distribution
max	An upper limit of uniform distribution
fix_leaf	A boolean specifying if the dates of the leaf nodes will be fixed at time 0 (i.e., at the most recent time). If TRUE, all samples will be drawn at the end of the simulation (i.e., from "today"). The default is FALSE.

Value

A named vector with random dates for each graph node
