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'm not sure what exactly you want here. If you want to write a function that uses some kind of algorithms on decision trees (e.g. CART) then you will have to consult some technical books. If you are just working on a practical problem, i.e. you have got a data set and just want to get a tree from it, then the tree or rpart package are two of the packages you can use (and you can consult "Modern Applied Statistics with S" by Venables and Ripley, 2002). I am not sure why you do not want to use the rpart package, but the tree package has some very good documentation which you can read and find out how to use it.
