Methods for objects of class "ts", typically the result of
ts.
# S3 method for ts
diff(x, lag = 1, differences = 1, …)# S3 method for ts
na.omit(object, …)
an object of class "ts" containing the values to be
differenced.
an integer indicating which lag to use.
an integer indicating the order of the difference.
a univariate or multivariate time series.
further arguments to be passed to or from methods.
For the na.omit method, a time series without missing values.
The class of object will be preserved.
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.
