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.
