Re: [R] kernlab | ksvm error

Thanks Uwe, Am I right that in ksvm's internal cross-validation, there is no guarantee for having *at least one* of each classes in each subset? Some randomness is involved, and when you get an unfortunate subsample > (e.g. if in the internal cross-validation one class is not selected at all) > it

Re: [R] Problem sourcing file
