Projections over the planes in PC space

This is a plot in 3D to see the orthogonal projections over the plane formed by first and second PC calculated with SVD. Once projected over the plane, projections arte projected again on the new axis (all them: terms or loadings,.....) to calculate the score for every PC.

Plot can be moved with the mouse so find the better view.

Data is centered so we see samples on both sides of the plane.
