This method initializes object by evaluating its associated
covariate(s) and grouping factor, if any is present, in data,
calculating various dimensions and constants used by optimization
algorithms involving corStruct objects (see the appropriate
Dim method documentation), and assigning initial values for
the coefficients in object, if none were present.
Usage
## S3 method for class 'corStruct':
Initialize(object, data, \dots)
Arguments
object
an object inheriting from class corStruct
representing a correlation structure.
data
a data frame in which to evaluate the variables defined in
formula(object).
...
this argument is included to make this method compatible
with the generic.
Value
an initialized object with the same class as object
representing a correlation structure.
