Autocorrelation Function
.DN
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'.
.CS
ACF(object, maxLag, ...)
.RA
.AG 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.
.OA
.AG maxLag
maximum lag for which the autocorrelation should be
calculated.
.AG ...
some methods for this generic require additional
arguments.
.RT
will depend on the method function used; see the appropriate documentation.
