logDet.reStruct: Extract reStruct Log-Determinants

Description

Calculates, for each of the pdMat components of object, the logarithm of the determinant of a square-root factor.

Usage

# S3 method for reStruct
logDet(object, …)

Arguments

object

an object inheriting from class "reStruct", representing a random effects structure and consisting of a list of pdMat objects.

…

some methods for this generic require additional arguments. None are used in this method.

Value

a vector with the log-determinants of square-root factors of the pdMat components of object.
