[R] Erros with RVM and LSSVM from kernlab library

[Noah Silverman]

Hello,

In my ongoing quest to develop a "best" model, I'm testing various forms 
of SVM to see which is best for my application.

I have been using the SVM from the e1071 library without problem for 
several weeks.

Now, I'm interested in RVM and LSSVM to see if I get better performance.

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'

Does this make sense to anyone?  Can you suggest how to resolve this?

Thanks!
