agraph: Create an admixture graph object.
In admixturegraph: Admixture Graph Manipulation and Fitting

Description Usage Arguments Value See Also Examples

Create an admixture graph object, an acyclic directed graph.

1 2	agraph(leaves, inner_nodes, parent_edges, admixture_proportions = extract_admixture_proportion_parameters(parent_edges))

`leaves`	The names of the leaves in the admixture graph. Do not use `(, )` or a single `R`.
`inner_nodes`	The name of the inner nodes in the admxture graph. Do not use `(, )` or a single `R` except for the root if you wish.
`parent_edges`	The list of edges in the graph, created by `parent_edges`.
`admixture_proportions`	The list of admixture proportions; created by `admixture_proportions`. Do not use `+, -, *, (, )`.
