In lmDiallel: Linear Fixed/Mixed Effects Models for Diallel Crosses

Create a Data Frame from All Combinations of Parentals

Description

This is a modification of the 'expand.grid()' function working specifically with diallel experiments. It creates a data frame from all combinations of the supplied vector of parents, depending on the mating scheme.

Usage

expand.diallel(pars, mating = 1)

Arguments

pars	pars a vector of parentals
mating	The type of mating scheme. 1: full diallel experiment; 2: no reciprocals; 3: no selfs; 4: no reciprocals and no selfs

Value

returns a data.frame object
