Usage

GetRelA(Ped = NULL, GenBack = 1, patmat = TRUE, List = FALSE)

Arguments

Ped	dataframe with columns id - dam - sire.
GenBack	number of generations back to consider; 1 returns parent-offspring and sibling relationships, 2 also returns grand-parental, avuncular and first cousins.
patmat	logical, distinguish between paternal versus maternal relative pairs? For avuncular pairs, the distinction is never made.
