# Number of Periods in Data

### Description

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

### Usage

1 2 3 4 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
