Description

Calculate the number of specified periods in a given time series like data object.

Usage

5
6
7
8

Arguments

x

A time-based object

Details

Essentially a wrapper to endpoints with the appropriate period specified; the resulting value derived from counting the endpoints

As a compromise between simplicity and accuracy, the results will always round up to the nearest complete period. So n**** - 1 will return the completed periods.

For finer grain detail one should call a higher frequency n**** function.

An alternative summary can be found with periodicity and unclass(periodicity(x)).

Value

The number of observations for the period type specified
