REC {lmDiallel}

Reciprocal Effect not parted into RGCA and RSCA

Description

Build incidence matrix to fit reciprocal effects in Griffing's model 1, 2, 4 (REC) and 3 (REC.G3) with lm function

Usage

REC(P1, P2, type = "fix", data)

Arguments

P1

a variable for the first parent

P2

a variable for the second parent

type

a variable for model selection. May be "fix" (fixed model) or "random" (random model).

data

a 'data.frame' where to look for explanatory variables

Details

a design matrix of n-1 parentals

Value

A design matrix for the reciprocal (REC) effect
