CalcRepeatability function

Parametric per trait repeatabilities

Estimates the variance in the sample not due to measurement error

CalcRepeatability(ID, ind.data)

Arguments

• ID: identity of individuals
• ind.data: individual measurements

Returns

vector of repeatabilities

Note

Requires at least two observations per individual

Examples

num.ind = length(iris[,1])
ID = rep(1:num.ind, 2)
ind.data = rbind(iris[,1:4], iris[,1:4]+array(rnorm(num.ind*4, 0, 0.1), dim(iris[,1:4])))
CalcRepeatability(ID, ind.data)
