selindex: Data for selection index

In plantbreeding: Analysis and visualization of data from plant breeding and genetics experiments

Description

The data illustrates development of selection index outlined by Smith(1936) as outlined in Singh and Chaudhary (1985) using function selection.index.

Usage

data(selindex)

Format

The data is list of threee matrix and a phenotypic dataframe.

$ X : phenotypic covariance matrix $ G : genotypic covariance matrix $ A : economic covariance matrix $ phenodf:'data.frame': 8 obs. of 5 variables: ..$ parents: parents ..$ trait1 : trait 1 ..$ trait2 : trait 2 ..$ trait3 : trait 3 ..$ trait4 : trait 4

Details

List of X, G, A, phenodf
