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.j48.J48 -F 5 -T 0.01 -S 1 -- -C 0.25 -M
2")))
and in both cases I get the following error:
Error in .jcall(filter, "Z", "setInputFormat", instances) :
method setInputFormat with signature (Lweka/core/Instances;)Z not
found
Thanks in advance,
Itziar Frades
