getHeritability: Calculate heritabilities from 'SpATS' objects

In SpATS: Spatial Analysis of Field Trials with Splines

Calculate heritabilities from SpATS objects

Description

For the genotype (when random), the function returns the generalized heritability proposed by Oakey (2006).

Usage

getHeritability(object, ...)

Arguments

object	an object of class SpATS as produced by SpATS()
...	further arguments passed to or from other methods. Not yet implemented.

Details

A numeric vector (usually of length 1) with the heritabilities.
