hi, i am a newbie to R
using rocr package to find out accuracy of a model using rpart
> perf.acc <- max(cust.rp.perf.acc at y.values[[1]])
Error: unexpected symbol in ;perf.acc  plot(cust.rp.perf.acc)
>plot(cust.rp.perf.acc)
how to interpret this graph on x-axis cutoff values and on y
-values-accuracy values are given .
thanks
