qpoint

Point on Stereonet

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

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

`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

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

List

`x`	coordinate on plot
`y`	coordinate on plot
