Description

Interactive extract axis point on Stereonet

Usage

AXpoint(UP = TRUE, col=2, n=1)

Arguments

UP	logical, TRUE=upper hemisphere
col	plotting color
n	maximum number to locate, default=unlimited

Details

Program uses locator to create a vector of poles. Points outside the focal sphere (r>1) are ignored. If n is missing, locator continues until stopped (middle mouse in linux, stop in windows).

Value

phiang	azimuth angle, degrees
dip	dip angle, degrees
x	x-coordinate of cartesian vector
y	y-coordinate of cartesian vector
z	z-coordinate of cartesian vector
gx	x-coordinate of prjection
gy	y-coordinate of prjection
