Sample median direction for a vector of circular data
Usage
circular_sample_median(x, axial = TRUE, na.rm = TRUE)
circular_sample_median_deviation(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.
