circular_summary: Circular Summary Statistics

In tectonicr: Analyzing the Orientation of Maximum Horizontal Stress

Circular Summary Statistics

Description

Circular mean, standard deviation, variance, quasi-quantiles, mode, 95% confidence angle, standardized skewness and kurtosis

Usage

circular_summary(x, w = NULL, kappa = NULL, axial = TRUE, na.rm = FALSE)

Arguments

x	numeric vector. Values in degrees.
w	(optional) Weights. A vector of positive numbers and of the same length as x.
kappa	numeric. von Mises distribution concentration parameter used for the circular mode. Will be estimated using est.kappa() if not provided.
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

named vector

Examples

data("nuvel1")
PoR <- subset(nuvel1, nuvel1$plate.rot == "na")
sa.por <- PoR_shmax(san_andreas, PoR, "right")
circular_summary(sa.por$azi.PoR)
circular_summary(sa.por$azi.PoR, w = 1 / san_andreas$unc)
