Principal stresses

Calculates the the principal stresses for a set of angular measurements.

dir_stats_ps(dir, dip)

Arguments

dir	A vector of dip directions measurements in degrees
dip	A vector of dip angles measurements in degrees

Value

A data frame with the dip direction and dip angle for the principal stresses

Details

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

Examples

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