    Lightbulb rWEKA problems downloading attribute selection methods

    Hi Everyone,

    I am trying to install Genetic search attribute selection method in rWEKA however i am not able to do so. I am not sure if this package is even available!

    I have tried the following and the error message is found underneath:

    WPM("load-package", "GeneticSearch")

    Error in WPM("load-package", "GeneticSearch") :
    Unavailable package 'GeneticSearch'.

    WPM("install-package", "GeneticSearch")
    [WekaPackageManager] Package GeneticSearch at version Latest doesn't seem to exist!

    GENETIC <- make_Weka_attribute_evaluator("weka.attributeSelection.GeneticSearch")
    Error in .jnew(name) : java.lang.ClassNotFoundException

    WOW("GeneticSearch")
    Error in .jnew(name) : java.lang.ClassNotFoundException

    This is not for just genetic linear forward i am having problems installing this as well! I would really like to use rWEKA for this so any help would be great!

    Thanks for any help
    Danielle

    Default

    I am trying to use genetic search in this context:

    AttributeSelectedClassifier <-make_Weka_classifier("weka.classifiers.meta.AttributeSelectedClassifier")
    result <-AttributeSelectedClassifier(CLASS~., Train_data,
    control = Weka_control(
    W = "weka.classifiers.trees.J48",
    E = "weka.attributeSelection.CfsSubsetEval",
    S = "weka.attributeSelection.GreedyStepwise"), na.action = NULL) ## HERE I WANT TO PUT GeneticSearch however it doesn't work


    print(result)
    evaluate_Weka_classifier(result, numFolds = 10)
