Dear R-developers,

I am trying to experiment with projection pursuit (PP), and different
indexes for the same, especially using the tourr package. However, I've
noticed that a PP index in the said package is only a function of the
projected data. Could I modify the function so that the index sees the
projection bases instead (or in addition to the data) ?

Alternatively, if some other package can be used this way, I would be
greatly obliged if you'd let me know.

Thanks and Regards,
