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.
random_dates(graph, min = 1000, max = 1000, fix_leaf = FALSE)An admixture graph
A lower limit of uniform distribution
An upper limit of uniform distribution
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.
A named vector with random dates for each graph node
