## 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).

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