If object includes a varStruct component, the inverse of
the standard deviations of the variance function structure represented
by the corresponding varFunc object are returned; else, a
vector of ones of length equal to the number of observations in the
data frame used to fit the associated linear mixed-effects model is
returned.
# S3 method for lmeStruct
varWeights(object)if object includes a varStruct component, a vector with
the corresponding variance weights; else, or a vector of ones.
an object inheriting from class "lmeStruct",
representing a list of linear mixed-effects model components, such as
reStruct, corStruct, and varFunc objects.
