seletion.index: Construction of selection index

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

Description

The function implements development of selection index outlined by Smith(1936) which is based on genetic and economic worth. The detail computation procedure is outlined by Singh and Chaudhary (1985).

Usage

seletion.index(phenodf, pcovmat, gcovmat, ecovmat, exout = TRUE, selectint = 0.01)

Arguments

phenodf	Matrix of phenotypic data
pcovmat	phenotypic covariance matrix
gcovmat	genotypic covariance matrix
ecovmat	matrix of economic value
exout	Whether to produce extended output to screen
selectint	Selection intensity
