⚠️There's a newer version (3.4-10) of this package.Take me there.

RFOC (version 3.4-6)

Graphics for Spherical Distributions and Earthquake Focal Mechanisms

Description

Graphics for statistics on a sphere, as applied to geological fault data, crystallography, earthquake focal mechanisms, radiation patterns, ternary plots and geographical/geological maps. Non-double couple plotting of focal spheres and source type maps are included for statistical analysis of moment tensors.
