[BioC] use selectWeka() for feature selection

[kai wang [guest]]

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?

Regards

Kai Wang
