In RFOC: Graphics for Spherical Distributions and Earthquake Focal Mechanisms

Point on Stereonet

Description

Plot a set of (azimuths, takeoff) angles on a stereonet.

Usage

qpoint(az, iang, col = 2, pch = 5, lab = "", POS = 4, UP = FALSE, PLOT = FALSE, cex = 1)

Arguments

az	vector of azimuths, degrees
iang	vector of incident angles, degrees
col	color
pch	plotting character
lab	text labels
POS	position for labels
UP	logical, TRUE=upper
PLOT	logical, add to existing plot
cex	character expansion of labels

Details

The iang argument represents the takeoff angle, and is measured from the nadir (z-axis pointing down).

Value

List

x	coordinate on plot
y	coordinate on plot
