Interesting package: anticlust

[llrs]

anticlust aims to something similar to what I do here. It is also on CRAN (3 months earlier than experDesign).
It has a strong(er) mathematical foundation: instead of randomly testing it uses some (smart?) algorithms.
It handles a bit worse the categorical variables but the authors have also worked on that.
In summary, it is a good package worth mentioning on the README (and perhaps to depend on it to extend it for spatial/plate distribution).
