Frank and list,
The reason I am trying to assign them is because I have a data set where i have arrived at the most likely model that describes the data and now I have another dataset where I know the factors but not the response. Therefore, surely I need to assign the predicted values to a response in order to say something like: Based on the model I believe unknown 1 is good, where as unknown 2 is very good etc? Maybe I am missing something or using the wrong approach but I thought the main purpose of using the predict function on new data was to "predict" the response?
