Details

Under various scenarios it is useful to know which people in a pedigree belong to the same paternal lines. This function first turns a pedigree into a graph where adjacency is defined by father-child relationships. Subsequently, the weakly connected components algorithm finds all the separate paternal lines and gives them an ID variable.
