The covariate(s) used in the calculation of the weights of the
variance function represented by object is (are) replaced by
value. If object has been initialized, value must
have the same dimensions as getCovariate(object).
Usage
## S3 method for class 'varFunc':
covariate(object) <- value
Arguments
object
an object inheriting from class varFunc,
representing a variance function structure.
value
a value to be assigned to the covariate associated with
object.
Value
a varFunc object similar to object, but with its
covariate attribute replaced by value.
