Calculate glsStruct Residuals

Description:

     The residuals for the linear model represented by 'object' are
     extracted.

Usage:

     ## S3 method for class 'glsStruct':
     residuals(object, glsFit, ...)

Arguments:

  object: an object inheriting from class 'glsStruct', representing a
          list of linear model components, such as 'corStruct' and
          'varFunc' objects.

  glsFit: an optional list with components 'logLik'   
          (log-likelihood), 'beta' (coefficients), 'sigma' (standard
          deviation for error term), 'varBeta' (coefficients'
          covariance matrix), 'fitted' (fitted values), and 'residuals'
          (residuals). Defaults to 'attr(object, "glsFit")'.

     ...: some methods for this generic require additional arguments. 
          None are used in this method.

Value:

     a vector with the residuals for the linear model represented by
     'object'.

Note:

     This method function is primarily used inside 'gls' and 
     'residuals.gls'.
