R: Calculate glsStruct Residuals

Calculate glsStruct Residuals

fitted(object, glsFit)

`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` (residuals), and `residuals` (residuals). Defaults to `attr(object, "glsFit")`.

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

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

This method function is generally only used inside gls and fitted.gls.
