Length of the smallest arc which contains all the observations.
The circular range is based on the sample circular distance.
Usage
circular_range(x, axial = TRUE, na.rm = TRUE)
Arguments
- x
numeric vector. Values in degrees.
- axial
logical. Whether the data are axial, i.e. pi-periodical
(TRUE, the default) or directional, i.e. \(2 \pi\)-periodical (FALSE).
- na.rm
logical value indicating whether NA values in x
should be stripped before the computation proceeds.
Value
numeric. angle in degrees
