AlphaRep function

Alpha repeatability

Calculates the matrix repeatability using the equation in Cheverud 1996 Quantitative genetic analysis of cranial morphology in the cotton-top (Saguinus oedipus) and saddle-back (S. fuscicollis) tamarins. Journal of Evolutionary Biology 9, 5-42.

AlphaRep(cor.matrix, sample.size)

Arguments

• cor.matrix: Correlation matrix
• sample.size: Sample size used in matrix estimation

Returns

Alpha repeatability for correlation matrix

Examples

#For single matrices
cor.matrix <- RandomMatrix(10)
AlphaRep(cor.matrix, 10)
AlphaRep(cor.matrix, 100)
#For many matrices
mat.list <- RandomMatrix(10, 100)
sample.sizes <- floor(runif(100, 20, 50))
unlist(Map(AlphaRep, mat.list, sample.sizes))
