Autocorrelation Function

Description:

     This function is generic; method functions can be written to
     handle specific classes of objects. Classes which already have
     methods for this function include: 'gls' and  'lme'.

Usage:

     ACF(object, maxLag, ...)

Arguments:

  object: any object from which an autocorrelation function can be
          obtained. Generally an object resulting from a model fit,
          from which residuals can be extracted.

  maxLag: maximum lag for which the autocorrelation should be
          calculated.

     ...: some methods for this generic require additional arguments.

Value:

     will depend on the method function used; see the appropriate
     documentation.
