dot-transform_procrustes: Procrustes Transform of Rectangular matrix

In baruuum/igplot: Fast(er) plotting for igraph objects

Description

Procrustes Transform of Rectangular matrix

Usage

.transform_procrustes(X, target, translation = TRUE, scale = TRUE)

Arguments

X	dense matrix to transform
target	dense matrix that is the target of the transform
translation	boolean; whether positions should be translated
scale	boolean; whether positions should be scaled

Value

returns a list of four elements:

1. the transformed matrix Xstar

2. the rotation matrix R

3. the translation vector t_vec

4. the scaling factor sigma

The transformed matrix Xstar can be recreated by the equation sigma * X * R if translation is FALSE. If translation is TRUE, adding t_vec to each row of the matrix sigma * X * R completes the transformation.
