circular_range function

Circular Range

Length of the smallest arc which contains all the observations.

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.

Returns

numeric. angle in degrees

Examples

roulette <- c(43, 45, 52, 61, 75, 88, 88, 279, 357)
circular_range(roulette, axial = FALSE)

data("san_andreas")
circular_range(san_andreas$azi)
