[R] Predict method of J48 in RWeka (Urgent)

[Priyanka Garg]

hi,

I am new to R using package RWeka.Currently i am using J48 classifier for
classification and prediction. My doubt is after building tree using J48,
when i use the same for prediction on my test set it gives the predicted
class names. How could i calculate accuracy, precision, recall and also
obtain laplace smoothing values ??
