head_t: Initial Subperiod

In andreas50/uts: Unevenly-spaced Time Series

Description

Return a subperiod time series with the initial part, where the length is specified in terms of the temporal length.

Usage

head_t(x, ...)

## S3 method for class 'uts'
head_t(x, width, ...)

Arguments

x	a time series object.
...	further arguments passed to or from methods.
width	a duration object, specifying the temporal width of the initial subperiod time series.

Methods (by class)

• uts: initial subperiod time seried for "uts" object.

Note

For an evenly spaced time series, the methods head() and head_t() essentially work the same. For unevenly spaced time series, however, they are quite different. The subperiod window of the former is determined by the observation values, while for the latter it is determined by the observation times.

See Also

head, tail, tail_t, window for other methods that extract a subperiod time series.

Examples

head_t(ex_uts(), ddays(1))
head_t(ex_uts(), ddays(0))  # leaves only the first observation
