Directional statistics for the 3D case

Description

Calculates the directional (spherical) statistics of a sample of directional measurements for the 3D case (plane with dip direction and dip angle or line with trend and plunge).

Usage

dir_stats_3D(dir, dip, conf.level = 0.95)

Arguments

dir

A vector of dip directions measurements in degrees

dip

A vector of dip angles measurements in degrees

conf.level

Confidence level to use for the cone of confidence (Default is 0.95)

Details

This always considers a plane expressed as dip direction and dip angle, it could be a bedding plane or a fault plane

Value

A data frame with the mean direction, mean dip angle, mean resultant length, spherical variance, concentration parameter, and cone of confidence

dir = c(12,18,22,15,10,20)
dip = c(42,40,48,30,42,30)
