add_graph_f4_sign: Extend a data frame with f_4 statistics predicted by a graph.
In admixturegraph: Admixture Graph Manipulation and Fitting

Description Usage Arguments Details Value

Extracts the sign for the f_4 statistics predicted by the graph for all rows in a data frame and extends the data frame with the graph f_4.

1	add_graph_f4_sign(data, graph)

`data`	The data frame to get the labels to compute the f_4 statistics from.
`graph`	The admixture graph.

The data frame, data, must contain columns W, X, Y, and Z. The function then computes the sign of the f4(W, X; Y, Z) statistics for all rows and adds these as a column, graph_f4_sign, to the data frame.

A data frame identical to data except with an additional column, graph_f4_sign, containing the sign of the f_4 statistics as determined by the graph.
