Why use numFold in evaluate_Weka_classifier of RWeka
Hi everyone,
I have a question about using RWeka package?
we know that instruction make_Weka_classifier that can help
us to build a model,and evaluate_Weka_classifier instruction
can help us to evaluate the performance of the model using on new data.
But I have a question about how to using the parameter numFold in
evaluate_Weka_classifier.Cross-validation means that using some parts
to

because the comments in the section that got modified
by 46821 are not optimal:

About classifier in RWeka
Hi everyone,
I have trouble to use RWeka, I tried: (w=weather dataset, all
preditors are nominal)
> m<-J48(play~., data=w)
> e<-evaluate_Weka_classifier(m,cost = matrix(c(0,2,1,0),
+ ncol = 2),numFolds = 10, complexity = TRUE,seed = 123,
+ class = TRUE)
it gives me exactly what I want, but when I tried the same classifier
on the other published data: (iris dataset has all numeric

RWeka problem: java.lang.NoSuchMethodError
Hi,
I'm trying to use RWeka and followed the following example from the
RWeka manual.
============
## Use some example data.
w <- read.arff(system.file("arff","weather.nominal.arff",
package = "RWeka"))
## Identify a decision tree.
m <- J48(play~., data = w)
m
## Use 10 fold cross-validation.
e <- evaluate_Weka_classifier(m,
cost = matrix(c(0,2,1,0),
