getTreeArcAngles

Description

Find the right (clockwise rotation, angle from +ve x-axis to furthest subtree nodes) and left (anti-clockwise angle from +ve x-axis to subtree) Returning arc angle in [0, 2] (0 to 360) domain.

Usage

getTreeArcAngles(df, origin_id, subtree)

Arguments

`df`	tree data.frame
`origin_id`	node id from which to calculate left and right hand angles of subtree.
`subtree`	named list of root id of subtree (node) and list of node ids for given subtree (subtree).

Value

named list with right and left angles in range [0,2] i.e 1 = 180 degrees, 1.5 = 270 degrees.
