Answer this only by using RStudio code:

The classification tree was trained with response data $Y$ and using two explanatory variables $x_1,x_2.$

A$)$ Sketch the classification implied by the tree in the region $[0,1{]}^2.$ Use "Yes"$/1$ and $"$No$"/0.$

B$)$ A new set of points has been provided with fresh response values, as follows.

Using the data and the trained tree, give predicted $(0/1)$ labels for the new points.

C$)$ Report the confusion matrix and performance measures TPR $=$ and FPR $=.$ Briefly comment

on the performance of this classifier.

D$)$ Can the given trained tree be trimmed to a simpler version, removing redundancies?

E$)$ Write a different tree that is equivalent to the given one.
