getEpiOffset {epinetr}

Retrieve epistatic offset.

Description

Retrieve offset used for calculating epistatic component.

Usage

getEpiOffset(pop)

Arguments

pop

A valid Population object with epistatic effects attached

Details

In order for the initial population to have an epistatic component with a mean of 0 for its phenotype, an offset is added, and it remains fixed across generations. This function retrieves that offset.

Examples

# Construct a new population with epistatic effects
pop <- Population(
  popSize = 20, map = map100snp, QTL = 20,
  broadH2 = 0.4, narrowh2 = 0, traitVar = 40,
  alleleFrequencies = runif(100, 0.05, 0.5)
)
pop <- attachEpiNet(pop)

# Find the epistatic contribution to the individuals' phenotypes
rowSums(getEpistasis(pop)) + getEpiOffset(pop)

# Compare with epistatic component from getComponents()
getComponents(pop)$Epistatic
