Dear all, I am trying to construct a wrapper that uses random forest to evaluate the subsets using RWeka and when I do: nombi <- make_Weka_filter("weka/attributeSelection/WrapperSubsetEval") datbin<- nombi(gene ~., data=X1X2X3X4W, control =Weka_control( B = list("weka.classifiers.trees.RandomForest"))) I also have tried with an other induction algorithm: datbin<- nombi(gene ~., data=X1X2X3X4W, control =Weka_control( B=list("weka.classifiers.trees.j4...

...forest to evaluate the subsets: I do: nombi <- make_Weka_filter("weka/filters/supervised/attribute/AttributeSelection") datbin<- nombi(gene ~., data=X1X2X4X5W, control =Weka_control( S=list("weka.attributeSelection.GeneticSearch"), E=list("weka.attributeSelection.WrapperSubsetEval"),B = list("weka.classifiers.trees.RandomForest"))) I get the following error: Exception in thread "main" java.lang.Exception: Illegal options: -B weka.classifiers.trees.RandomForest at weka.core.Utils.checkForRemainingOptions(Unknown Source) at weka.fil...
