Hi,
Could you please tell me whether there is a difference in the result of svm
when using formula instead of class label?
Well, a factor object (where you have class labels in) is not
sufficient, you also need explaining variables.
The formula interface is just a convenient way to specify the things.
The results should be the same since in most cases the formula method of
some generic calls the matrix or default method later on ...
