pdMatrix.reStruct: Extract Matrix or Square-Root Factor from Components of an
reStruct Object
Description
This method function extracts the positive-definite matrices
corresponding to the pdMat elements of object, or
square-root factors of the positive-definite matrices.
Usage
# S3 method for reStruct
pdMatrix(object, factor)
Value
a list with components given by the positive-definite matrices
corresponding to the elements of object, or square-root factors
of the positive-definite matrices.
Arguments
object
an object inheriting from class "reStruct",
representing a random effects structure and consisting of a list of
pdMat objects.
factor
an optional logical value. If TRUE, square-root
factors of the positive-definite matrices represented by the elements
of object are returned; else, if FALSE, the
positive-definite matrices are returned. Defaults to FALSE.
