It's likely that class is numeric and you actually want factor (regression tree vs classification tree).
str(echoknn.train) will show you. By saying, "I have to build a tree classifier" you make me think that this is a course assignment. If it is, you should perhaps talk to your instructor. If not, then a more detailed and reproducible example will usually get you a more informative answer, since it will allow people to actually run and debug your code.
