Length of the smallest arc which contains all the observations.

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
