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)
.
# S3 method for varFunc
covariate(object) <- value
an object inheriting from class "varFunc"
,
representing a variance function structure.
a value to be assigned to the covariate associated with
object
.
a varFunc
object similar to object
, but with its
covariate
attribute replaced by value
.
# NOT RUN {
vf1 <- varPower(1.1, form = ~age)
covariate(vf1) <- Orthodont[["age"]]
# }
