Hi, I'm trying to solve simple problem. How to pass arguments to specific search method in RWeka package using BayesNet classifier. Here is code example:
BNet <- make_Weka_classifier("weka/classifiers/bayes/BayesNet") K2="weka.classifiers.bayes.net.search.local.K2" wcontrol <- Weka_control(D=TRUE,Q=list(K2,P=2)) model <- BNet(target~., data=train.df, control=wcontrol) if I run this code it will complain Error in .jcall(classifier, "V", "buildClassifier", instances) : java.lang.Exception: Can't find class called: weka.classifiers.bayes.net.search.local.K2 -P 2 Calls: BNet ... RWeka_build_classifier -> .jcall -> .jcheck -> .Call I know that arguments can be passed via Weka_control, and it works if I just use search method, e.g. wcontrol <- Weka_control(D=T,Q=K2) and here D=T option works too. What it should do is to pass additional -- after K2 class. According to http://www.cs.waikato.ac.nz/~remco/weka.bn.pdf and using java command it should looks like this: java weka.classifiers.bayes.BayesNet -t iris.arff -D -Q weka.classifiers.bayes.net.search.local.K2 -- -P 2 I tried to append double dash to K2 definition, e.g. K2="weka.classifiers.bayes.net.search.local.K2 --" but still out of luck. Any suggestions? Thanks, Valentin. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
