extract_admixture_proportion_parameters

Matrix created with the <code>agraph_parents</code> function.

parent_edges


This function is simply selecting the edges with admixture proportion specifications
so these can be handled when building a graph using <code>agraph</code>. It is not a function
you would need to call explicitly, rather it is there to allow people <em>not</em> to use
it to provide admixture proportions explicitly (which we normally wouldn't recommend).


Implements tools for building and visualising admixture graphs
and for extracting equations from them. These equations can be compared to f-
statistics obtained from data to test the consistency of a graph against data --
for example by comparing the sign of f_4-statistics with the signs predicted by
the graph -- and graph parameters (edge lengths and admixture proportions) can
be fitted to observed statistics.

extract_admixture_proportion_parameters: Extract the admixture proportion parameter from edge specifications.
