Week 8 To Do's

[dicook]

• [x] making givens_full_path run everything, so then make other functions not exported
• [x] generate torus code (DI)
• [x] fix is_orthonormal in tourr (DI)
• [x] calculate tau needs expanding to two angles, when d=2
• [x] construct rotation matrix generates 2
• [x] multiplication multiplies the two matrices and then the data
• [x] tau1 and tau2 are divided into steps, to generate moving planes

Oh, tourr::basis_random() produces an othonormal basis, so there is no need to wrap this in tourr::orthonormalise(). So all example code can be simplified

[dicook]

The code for generating the torus is in preprojection_example.R, you can add this into generate_space_view() for when d=2.

Ahhhh,orthonormalisation_by()needed to completely do the orthonormalisation. All is good now when you re-install the tourr package @zolabat

Thank you. It works perfectly. Now I'm working on 2D.

I was wondering if the update in tourr_0.6.1 version? It's the lastest CRAN version but orthonormalise_by() function seems not updated. I could be wrong. @dicook

[zolabat]

It turns out there are 5 different angles and rotation matrices involved in the case of 2D. Completed the tasks above in try_2d.R file.

You need to use the GitHub version of tourr: https://github.com/ggobi/tourr (sorry, just saw this now)
