[R] projection pursuit classification

2012-04-16 Thread Ranjan Maitra 
Hello,

I am trying to look at projection pursuit classification: I was
wondering what function/package is recommended for use. I note that the
stats function ppr only takes in numeric responses. 

Any suggestions?

Many thanks,
Ranjan

Tree.result - PP.Tree(LDA,iris[train,5],iris[train,1:4])


These are *Warning* messages rather than error messages. These warnings 
come from coding problems in the functions you are using (PP.Tree or 
those PP.Tree depends on), whatever PP.Tree() is
