plotmanyfoc: Plot Many Focals

In RFOC: Graphics for Spherical Distributions and Earthquake Focal Mechanisms

Plot Many Focals

Description

Plot a long list of focal mechanisms

Usage

plotmanyfoc(MEK, PROJ, focsiz = 0.5, foccol = NULL,
UP=TRUE, focstyle=1, PMAT = NULL, LEG = FALSE, DOBAR = FALSE)

Arguments

MEK	List of Focal Mechanisms, see details
PROJ	Projection
focsiz	focal size, inches
foccol	focal color
UP	logical, UP=TRUE means plot upper hemisphere (DEFAULT=TRUE)
focstyle	integer, 1=beach ball, 2=nipplot, 3=strike-slip, 4=P-T, 5=P, 6=T
PMAT	Projection Matrix from persp
LEG	logical, TRUE= add focal legend for color codes
DOBAR	add strike dip bar at epicenter

Details

Input MEK list contains

MEKS = list(lon=0, lat=0, str1=0, dip1=0, rake1=0, dep=0, name="", Elat=0, Elon=0)
