adc.mq.jack: An ADC model with MINQUE analyses and jackknife tests
In qgtools: Generalized Quantitative Genetics Data Analyses

Description Usage Arguments Details Value Author(s) References Examples

An AD model can be analyzed by MINQUE approach, requiring no specific genetic mating design or balance data. For reliable results, parents and F1s, parents and F2s, are preferred.

1	adc.mq.jack(Y, Ped, JacNum = NULL, JacRep = NULL)

`Y`	A trait matrix including one or more traits.
`Ped`	A pedigree matrix including Env, Female, Male, Generation, with or without block is required. The matrix should include either 4 or 5 columns.
`JacNum`	Number of groups to be jackknifed. The default is 10.
`JacRep`	Repeating times for jackknife process. The default is 1.

A pedigree matrix used for analysis is required in the order of Environment (column 1), Female(column 2), Male(column 3), Generation (column 4). Column 5 for block can be default. Even though there is only one environment, this column is needed. Please refer to the example.
