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.
