R: Circular Range

circ.range {CircStats} | R Documentation

## Circular Range

### Description

Computes the circular range of a data set and performs a test of uniformity if specified.

### Usage

    circ.range(x, test=FALSE)

### Arguments

`x` | vector of directional data measured in radians.
`test` | logical flag: if TRUE then the test of uniformity is performed; otherwise the test is not performed. Default is FALSE.

### Details

The circular range is the shortest arc on the circle containing the entire set of data. The p-value is computed using the exact distribution of the circular range under the hypothesis of uniformity.

### Value

Returns a dataframe with the circular range, r. If the significance test is requested the p-value of the test is returned as p.value.

### Note

nCk(n,k) evaluate combinatoric, it should not be called by the users.
