Initialize.glsStruct {nlme}R Documentation

Initialize a glsStruct Object

Description

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

Usage

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

Arguments

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, qrTol = .Machine$single.eps), implying that linear dependencies are not allowed in the model and that the tolerance for detecting linear dependencies among the columns of the regression matrix is .Machine$single.eps.
... some methods for this generic require additional arguments. None are used in this method.

Value

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