Details

‘⁠triax.abline⁠’ displays one or more lines on a triangle plot. Lines are oriented in the conventional way, horizontal for the left axis, slanting up to the right for the right axis and up to the left for the bottom axis. If ‘⁠cc.axes⁠’ is TRUE, the orientation is up-left for the left axis, horizontal for the right axis and up-right for the bottom axis.

Remember to call ‘⁠triax.plot⁠’ with ‘⁠no.add=FALSE⁠’ and restore the graphics parameters as in the example or the lines will not be placed properly.

Value

nil
