Usefulness criterion

Calculates the usefulness criterion

Usage

usefulness(
  pop,
  trait = 1,
  use = "gv",
  p = 0.1,
  selectTop = TRUE,
  simParam = NULL,
  ...
)

Arguments

pop

and object of Pop-class or HybridPop-class

trait

the trait for selection. Either a number indicating a single trait or a function returning a vector of length nInd.

use

select on genetic values (gv, default), estimated breeding values (ebv), breeding values (bv), or phenotypes (pheno)

p

the proportion of individuals selected

selectTop

selects highest values if true. Selects lowest values if false.

simParam

an object of SimParam

...

additional arguments if using a function for trait

Value

Returns a numeric value

Examples

#Create founder haplotypes
founderPop = quickHaplo(nInd=2, nChr=1, segSites=10)

#Set simulation parameters
SP = SimParam$new(founderPop)
SP$addTraitA(10)

#Create population
pop = newPop(founderPop, simParam=SP)

#Determine usefulness of population
usefulness(pop, simParam=SP)
#> [1] 1

#Should be equivalent to GV of best individual
max(gv(pop))
#> [1] 1
