This is not the name for the class variable of the wiris data from R.

Why do you construct this in a so complicated manner rather than typing 
the formula directly?

naiveBayes sort of fails (well, it runs smoothly but the result won't 
make sense) here since it expects a class variable.

Works for me.


Please upgrade R, e1071 and run in a clean session to see that the code 
above does not fail. Although it makes absolutely no sense.
