I guess you're using the svm in the e1071 package?
What's svmtrain?

The call to "svm" trains the svm.
The call to predict uses it on new data, but you need to give it new  
data to predict on. You have:

p <- predict(m)

What exactly do you want your model to do? Predict on what?

Please see the code in the Examples section of ?svm .. it's pretty  
straight forward. Let us know what problems you're having  
understanding those examples and we can try to offer some insight.
