COI: Inbreeding coefficient

In EstimateBreed: Estimation of Environmental Variables and Genetic Parameters

Inbreeding coefficient

Description

Function for calculating the inbreeding coefficient

Usage

COI(var, VG, VF, generation = "all", verbose = FALSE)

Arguments

var	Column with the variable name
VG	Column with genotypic variance
VF	Column with phenotypic variance
generation	Parameter to select the generation. Use 'all' to get the parameters for all the generations or 'F3', 'F4', 'F5' and 'F6' for just one of the generations.
verbose	Logical argument. Runs the code silently if FALSE.

Value

Returns the total, additive and dominance variance values based on the variance components for a given variable.

Examples

library(EstimateBreed)

var <- c("A","B","C","D","E")
VF <- c(2.5, 3.0, 2.8, 3.2, 2.7)
VG <- c(1.2, 1.5, 1.3, 1.6, 1.4)
data <- data.frame(var,VG,VF)

#Calculating for all generations
inbr1 <- with(data,COI(var,VG,VF,generation = "all"))

#Calculating for just one generation
inbr2 <- with(data,COI(var,VG,VF,generation = "F3"))
