solve.reStruct: Apply Solve to an reStruct Object

Description

Solve is applied to each pdMat component of a, which results in inverting the positive-definite matrices they represent.

Usage

# S3 method for reStruct
solve(a, b, …)

Arguments

a

an object inheriting from class "reStruct", representing a random effects structure and consisting of a list of pdMat objects.

b

this argument is only included for consistency with the generic function and is not used in this method function.

…

some methods for this generic require additional arguments. None are used in this method.

Value

an reStruct object similar to a, but with the pdMat components representing the inverses of the matrices represented by the components of a.

Examples

# NOT RUN {
rs1 <- reStruct(list(A = pdSymm(diag(1:3), form = ~Score),
  B = pdDiag(2 * diag(4), form = ~Educ)))
solve(rs1)
# }
