Calculate the left-right position wrt to the symmetrised MANC midline

Usage

manc_lr_position(x, ...)

Arguments

x: An object containing XYZ vertex locations in microns, compatible with xyzmatrix
...: Additional arguments passed to xform

Value

A vector of point displacements in microns where 0 is at the midline and positive values are to the fly's right.
