Use sorted pedigree to calculate a numerator relationship matrix based on a tabular method, where the individuals in Progeny must be ordered genealogically. The missing Sire and Dam are coded as 0.

1	computeA(Progeny, Sire, Dam)

`Progeny`	A numeric vector of sorted progenies.
`Sire`	A numeric vector of sires according to progenies in `Progeny` column.
`Dam`	A numeric vector of dams according to progenies in `Progeny` column.

A n by n numerator relationship matrix, where n refers to total number of individuals in Progeny column.
