findfamilies(x, threshold = 0.4)
Arguments
x
The nxn correlation matrix of the input dataset.
threshold
This threshold is used to identify close-degree relatives. Recommended values are 0.4 to identify first-degree relatives, and 0.15 to identify first- and second-degree relatives.
Value
Output numerical family ID for each individual. Individuals with the same ID are judged to be family members.
