# intradayFrequencies: R support for Intraday frequencies In tis: Time Indexes and Time Indexed Series

## Description

create `tif` (TimeIndexFrequency) codes for hourly, minutely, and secondly `ti`'s.

## Usage

 ```1 2 3``` ``` hourly(n = 0) minutely(n = 0) secondly(n = 0) ```

## Arguments

 `n` number of base periods to skip. That is, `hourly(2)` gives a `tif` code for a series observed every 2nd hour, while both `minutely()` and `minutely(1)` are for a series observed once per minute, `secondly(30)` means every 30 seconds, and so on.

## Details

The current implementation has hourly(n) –> 2000 + n, minutely(n) –> 3000 + n, and secondly(n) –> 4000 + n. If `n` divides evenly into 3600 for `secondly(n)`, the return code will be the same as `hourly(n/3600)`. For `secondly(n)` and `minutely(n)`, if `n` divides evenly into 60, the return code will be as if `minutely(n/60)` or `hourly(n/60)` had been called, respectively.

For `hourly(n)`, `n` must evenly divide into 24 and be less than 24, i.e., `n` is one of 1, 2, 3, 4, 6, 8, 12. For `minutely(n)`, `n` must be an even divisor of 1440, and less than 720. For `secondly(n)`, `n` must divide evenly into 86400, and be no larger than 960.

## Value

An integer `tif` code.
