R help - Dec 2009 - problem with RWeka Weka_control RandomForest

Dear All,



I am finding trouble trying to guild a Wrapper using random 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.filters.supervised.attribute.AttributeSelection.setOptions(Unknown
Source)



I tryied specifying more parameters and got the same error:



I do:

datbin<- nombi(gene ~., data=X1X2X3X4W,  control =Weka_control(
S=list("weka.attributeSelection.GeneticSearch"),
E=list("weka.attributeSelection.WrapperSubsetEval"),B
list("weka.classifiers.trees.RandomForest -F 5 -T 0.01 -R 1 -- -I 10 -K
0 -S 1")))



I get the following error:

Exception in thread "main" java.lang.Exception: Illegal options: -B
weka.classifiers.trees.RandomForest -F 5 -T 0.01 -R 1 -- -I 10 -K 0 -S 1

Dear All,



I am finding trouble trying to build a Wrapper using random 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:

I tryied specifying more parameters and got the same error:



I do:

datbin<- nombi(gene ~., data=X1X2X3X4W,  control =Weka_control(

E=list("weka.attributeSelection.WrapperSubsetEval"),B
list("weka.classifiers.trees.RandomForest -F 5 -T 0.01 -R 1 -- -I 10 -K
0 -S 1")))



I get the following error:

The error is fairly explicit, isn't it? There is no -B option for 
AttributeSelection, see
   WOW("weka/filters/supervised/attribute/AttributeSelection")
