satisfies_zerof4 | R Documentation |
This function returns TRUE
if and only if the admixture graph is compatible with
the f4-statistics listed in nonzero_f4
being non-zero
satisfies_zerof4(graph, zero_f4)
graph |
An admixture graph |
zero_f4 |
A data frame or matrix with four columns. One row for each f4-statistic which is expected to be zero |
TRUE
if all constraints are satisfied, else FALSE
