Initialize.glsStruct

Initialize a glsStruct Object

The individual linear model components of the glsStruct list are initialized.

## S3 method for class 'glsStruct'
Initialize(object, data, control, ...)

`object`	an object inheriting from class `"glsStruct"`, representing a list of linear model components, such as `corStruct` and `varFunc` objects.
`data`	a data frame in which to evaluate the variables defined in `formula(object)`.
`control`	an optional list with control parameters for the initialization and optimization algorithms used in `gls`. Defaults to `list(singular.ok = FALSE)`, implying that linear dependencies are not allowed in the model.
`...`	some methods for this generic require additional arguments. None are used in this method.

a glsStruct object similar to object, but with initialized model components.
