\name{logDet.reStruct}
\title{Extract reStruct Log-Determinants}
\usage{
\method{logDet}{reStruct}(object, \dots)
}
\alias{logDet.reStruct}
\arguments{
\item{object}{an object inheriting from class \code{reStruct},
representing a random effects structure and consisting of a list of
\code{pdMat} objects.}
\item{\dots}{some methods for this generic require additional
arguments. None are used in this method.}
}
\description{
Calculates, for each of the \code{pdMat} components of \code{object},
the logarithm of the determinant of a square-root factor.
}
\value{
a vector with the log-determinants of square-root factors of the
\code{pdMat} components of \code{object}.
