Stress Grid — stereo_stress_grid • structr

Plots the slip directions for a grid of fault plane normals and a given stress tensor in a stereographic/equal-area projection

Usage

stereo_stress_grid(sigma, n = 15, radius = NULL, ...)

Arguments

sigma: symmetric 3x3 matrix. The (reduced) stress tensor.
n: integer. The size of the grid of fault planes. 20 by default.
radius: numeric. Radius of circle. Defaults to getOption("structr.radius").
...: optional arguments passed to stereo_hoeppener()

Value

object of class "Fault"
