Hello.

I have a hudge problem, don't know how to deal with it...

I'm supposed to implement a tree structure in R, without using

rpart library...

I don't have any clue about appropriate approach...

Anyway, I can't use pointers under R...so how to to it?

lists, vectors...

Anyway, does anybody knows how the regression tree in rpart was

implemented...

Someone please help!

Thanks,

ana
