Value

the function returns a list containing

$sel$pop.sel

the selected males and females.

$sel$ps

if ps <= 1, fraction selected in selection of males and females; if ps > 1, ps is number of selected males and females.

$sel$decr

whether the sort order is decreasing.

$sel$sel.crit

the selection criteria, it can be "TBV", "TGV", and "pheno".

$sel$sel.single

the single-trait selection method, it can be "ind", "fam", "infam", and "comb".

$sel$sel.multi

the multiple-trait selection method, it can be "index", "indcul", and "tmd".

$sel$index.wt

the weight of each trait for multiple-trait selection.

$sel$index.tdm

the index of tandem selection for multiple-trait selection.

$sel$goal.perc

the percentage of goal more than the mean of scores of individuals.

$sel$pass.perc

the percentage of expected excellent individuals.

Examples

# Generate annotation simulation parameters
SP <- param.annot(qtn.num = list(tr1 = 10))
# Generate genotype simulation parameters
SP <- param.geno(SP = SP, pop.marker = 1e4, pop.ind = 1e2)
# Generate phenotype simulation parameters
SP <- param.pheno(SP = SP, pop.ind = 100)
# Generate selection parameters
SP <- param.sel(SP = SP, sel.single = "ind")

# Run annotation simulation
SP <- annotation(SP)
# Run genotype simulation
SP <- genotype(SP)
# Run phenotype simulation
SP <- phenotype(SP)
# Run selection
SP <- selects(SP)
