Methods for Time Series Objects

Description:

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

Usage:

     ## S3 method for class 'ts':
     diff(x, lag = 1, differences = 1, ...)

     ## S3 method for class 'ts':
     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.
