Matrix.reStruct: 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 method for 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.

Examples

# NOT RUN {
rs1 <- reStruct(list(Dog = ~day, Side = ~1), data = Pixel)
matrix(rs1) <- list(diag(2), 3)
# }
