can everyone tell's me .. how to make output of rpart growing the tree into table .. with the column
node), split, n, loss, yval, (yprob)
* denotes terminal node
and the values
1) root 223 48 UMUM (0.21524664 0.78475336)
2) PT.Kabupaten>=0.5 44 0 KHUSUS (1.00000000 0.00000000) *
3) PT.Kabupaten< 0.5 179 4 UMUM (0.02234637 0.97765363) *
the next question some like the first question ,, and now how to make this output readable with make the output into table
summary(rpart)
