Matrix.reStruct {nlme} | R Documentation |
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.
## S3 method for class 'reStruct': matrix(object) <- value
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 . |
an reStruct
object similar to object
, but with the
coefficients of the individual pdMat
components modified to
produce the matrices listed in value
.
