## Auxiliary functions used by gls

### Description

These are functions used by `gls` to call its compiled C code. They are exported to allow experimentation with modified versions.

### Usage

    glsApVar(glsSt, sigma, conLin = attr(glsSt, "conLin"),
             .relStep = .Machine$double.eps^(1/3), minAbsPar = 0, natural = TRUE)
    glsEstimate(object, conLin = attr(object, "conLin"),
                control = list(singular.ok = FALSE))

### Arguments

`glsSt, object` | An object inheriting from class `"glsStruct"`.
`sigma` | the estimated residual standard error: see `glsObject`.
`conLin` | A ‘condensed linear model’: see `logLik.glsStruct`.
`.relStep, minAbsPar, natural` | Control values: see `glsControl`.
`control` | The relevant part of a `glsControl` return value.
