Thanks David,

Then, do you have any clue why RVM or LSSVM would be generating an error?

My original post was:


"When running RVM or LSSVM on the exact same data as the SVM{e1071}, I 
get an error that I don't understand:
Error in .local(x, ...) : kernel must inherit from class 'kernel' "

Any suggestions?

Thanks!
