R: Rayleigh Test of Uniformity: General Unimodal Alternative

r.test {CircStats} | R Documentation

## Rayleigh Test of Uniformity: General Unimodal Alternative

### Description

Performs a Rayleigh test of uniformity, assessing the significance of the mean resultant length. The alternative hypothesis is a unimodal distribution with unknown mean direction and unknown mean resultant length.

### Usage

    r.test(x, degree=FALSE)

### Arguments

`x` | vector of angular measurements in radians.
`degree` | logical flag: if TRUE, data is assumed to be measured in degrees rather than radians. Default is FALSE.

### Value

Returns a list with two components: the mean resultant length, r.bar, and the p-value of the test statistic, p.value.
