Examples of weka.core.Capabilities

weka.core.Capabilities
the classifier handle the data? getCapabilities().testWithFail(instances); ... // possible deletion of instances with missing class labels, etc. For only testing a single attribute, use this:
```
 ... Attribute att = instances.attribute(0); getCapabilities().testWithFail(att); ... 
```
Or for testing the class attribute (uses the capabilities that are especially for the class):
```
 ... Attribute att = instances.classAttribute(); getCapabilities().testWithFail(att, true); ... 
```
