nipXY: Fault-Slip vector plot

Description

Plots a fault plane and the slip vector. Used for geographic representation of numerous focal spheres.

Usage

nipXY(MEC, x = x, y = y, focsiz=1, fcol = gray(0.9), nipcol = "black", cex = 0.4)

Value

LIST

Q

output of qpoint

N

slip vector

Arguments

MEC

MEC structure

x

focsiz

size in inches

fcol

color for plotting

nipcol

color of slip point

cex

character expansion for slip point
