R Documentation

Assign Matrix to a pdMat or pdBlocked Object

Description

The positive-definite matrix represented by object is replaced by value. If the original matrix had row and/or column names, the corresponding names for value can either be NULL, or a permutation of the original names.

Usage

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

Arguments

`object`	an object inheriting from class `"pdMat"`, representing a positive definite matrix.
`value`	a matrix with the new values to be assigned to the positive-definite matrix represented by `object`. Must have the same dimensions as `as.matrix(object)`.

Value

a pdMat or pdBlocked object similar to object, but with its coefficients modified to produce the matrix in value.
