Methods for Time Series Objects

Description:

     Methods for objects of class `"ts"', typically the result of `ts'.

Usage:

     diff(x, lag=1, differences=1, ...)
     na.omit(object, ...)

Arguments:

       x: an object of class `"ts"' containing the values to be
          differenced.

     lag: an integer indicating which lag to use.

differences: an integer indicating the order of the difference.

  object: a univariate or multivariate time series.

     ...: further arguments to be passed to or from methods.

Details:

     The `na.omit' method omits initial and final segments with missing
     values in one or more of the series.  `Internal' missing values
     will lead to failure.

Value:

     For the `na.omit' method, a time series without missing values.
     The class of `object' will be preserved.
