Hi, I'm trying to use selectWeka() from BioSeqClass to do feature selection. But there's an error as below: > trainset=read.csv('D:\\7617_des.csv', header = TRUE) > data=trainset[,1:313] > class=trainset[,314] > input=data.frame(data,class) > result=selectWeka(input,evaluator=SVMAttributeEval,search="Ranker",50) Error in paste("java -cp ", file.path(path.package("BioSeqClass"), "scripts", : object 'SVMAttributeEval' not found How to fix it?
