\name{Initialize.glsStruct}
\title{Initialize a glsStruct Object}
\usage{
\method{Initialize}{glsStruct}(object, data, control, \dots)
}
\alias{Initialize.glsStruct}
\arguments{
 \item{object}{an object inheriting from class \code{glsStruct},
   representing a list of linear model components, such as
   \code{corStruct} and \code{varFunc} objects.}
 \item{data}{a data frame in which to evaluate the variables defined in
   \code{formula(object)}.}
 \item{control}{an optional list with control parameters for the
   initialization and optimization algorithms used in
   \code{gls}. Defaults to \code{list(singular.ok = FALSE, qrTol =
     .Machine$single.eps)}, implying that linear dependencies are not
   allowed in the model and that the tolerance for detecting linear
   dependencies among the columns of the regression matrix is
   \code{.Machine$single.eps}.}
 \item{\dots}{some methods for this generic require additional
    arguments.  None are used in this method.} 
}

\description{
  The individual linear model components of the \code{glsStruct} list
  are initialized.  
}
\value{
  a \code{glsStruct} object similar to \code{object}, but with
  initialized model components. 
}
