    I'm using the tree package to fit one tree from a training set.
    I'm using the command:
        hm.tr <-tree(X1~.,teste2, mindev = 0, minsize = 2)        
    and i get the error:

    Error in "row.names<-.data.frame"(*tmp*, value = fit$node[1:n]) : 
            duplicate row.names are not allowed

    the frameset, has 180 columns and 16000 rows.
    The first column, takes a value from 42..61 and the others 0 or 1.

    Any help will be apreciated.



    P.s. I'm using R1.3.0 in a winnt machine
