breeding_values(data, fitted)

## S3 method for class 'qtlpoly.bvalues'
plot(x, pheno.col = NULL)

Arguments

data

an object of class qtlpoly.data.

fitted

an object of class qtlpoly.fitted.

x

an object of class qtlpoly.bvalues to be plotted.

pheno.col

a numeric vector with the phenotype column numbers to be plotted; if NULL, all phenotypes from 'data' will be included.

Value

An object of class qtlpoly.bvalues which is a list of results for each trait containing the following components:

pheno.col

a phenotype column number.

y.hat

a column matrix of breeding value for each individual.

A ggplot2 histogram with the distribution of breeding values.
