In Momocs: Morphometrics using R

Register new baselines

Description

A non-exact baseline registration on t1 and t2 coordinates, for the ldk1-th and ldk2-th points. By default it returns Bookstein's coordinates.

Usage

coo_baseline(coo, ldk1, ldk2, t1, t2)

Arguments

coo	matrix of ⁠(x; y)⁠ coordinates or any Coo object.
ldk1	numeric the id of the first point of the new baseline
ldk2	numeric the id of the second point of the new baseline
t1	numeric the (x; y) coordinates of the 1st point of the new baseline
t2	numeric the (x; y) coordinates of the 2nd point of the new baseline

Value

a matrix of (x; y) coordinates or a Coo object.
