R Documentation

Assign reStruct Matrices

Description

The individual matrices in value are assigned to each pdMat component of object, in the order they are listed. The new matrices must have the same dimensions as the matrices they are meant to replace.

Usage

## S3 replacement method for class 'reStruct'
matrix(object) <-  value

Arguments

`object`	an object inheriting from class `"reStruct"`, representing a random effects structure and consisting of a list of `pdMat` objects.
`value`	a matrix, or list of matrices, with the new values to be assigned to the matrices associated with the `pdMat` components of `object`.

Value

an reStruct object similar to object, but with the coefficients of the individual pdMat components modified to produce the matrices listed in value.
