I am new to the R thing.

I have been building this decision tree in TreeAge and it's OK. Now, i have this Tree here:

I have this decision to make:

                A patient with Cancer 

                    /                   \
         Cure Immediately              Wait a little
        /                \            /              \
     Alive              Dead        Alive             Dead
 D_p_Alive                #            #             p_progress

The values below are the probabilities for each decision... could you please give me a hand on how to build this tree, i sincerely have no clue, even after going 1 week on reading..

I read about decision trees, how to prune them, about rpart, cran etc...

Thanks in advance..
