using rpart with a tree misclassification condition
...f I have in the root 100 observations, 90 from group 0 and 10
from group 1, I want that in the final tree a maximum of 9 and 1
observations out of group 0 and 1, respectively, will be misclassified.
Does anyone know what code will be appropriate for implementing this
condition?
Thank you in advance
Meytar

plotting several ROC curves on the same graph
...t;,sens","spec",iterationnumber.")
and I have for each ROC curve a different matrix but all matrices have the
same
size. (They are organized as a list of 10 matrices by the size 4X4 each)
Would appreciate your help in putting all ROC curves on the same plot.
Thank you
