Variance Weights for glsStruct Object
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 model is returned.
## S3 method for class 'glsStruct' varWeights(object)
if object includes a varStruct component, a vector with
the corresponding variance weights; else, or a vector of ones.
