Description Usage Arguments Value Author(s) Examples

Use sorted pedigree to calculate numerator relationship matrix, where the individual in Progeny must be ordered from old to young. 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.
