graph_environment

The parameters of a graph as returned by
<code><a rd-options="" href="/link/extract_graph_parameters?package=admixturegraph&version=1.0.2" data-mini-rdoc="admixturegraph::extract_graph_parameters">extract_graph_parameters</a></code>.

parameters

If specified, a vector of edge lengths. Otherwise
defaults are used.

edge_lengths

If specified, a vector of admixture proportions.
Otherwise defaults are used.

admix_prop


Constructs an environment in which the $f$ statistics for a graph can be
evaluted, based on the parameters in a graph and values for edge lengths and
admixture proportions (with defaults if not specified).


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.
