"Class Value" for classifier? How to assign id to data set element

[johnpaulashenfelter]

Support request -- sorry!

I'm using the classifier on a data set pulled from a database. Let's say it looks like this (details don't really matter)

labels = [quiz1_points, quiz2_points, quiz3_points, quiz4_points]
data = [
[10,3,0,22], # this is user_id = 15
[5,1,5,16], # this is user_id 55
etc..
]

The classifier works great to sort the users into, say 4 groups.

Is there any way to get the user_ids for each group without looping through and using eval([10,3,0,22]) to find that its in group 1?

Is that what a "class value" is for? Data sets have the last element as the "class value"..

Same question - did you figure out how to do this?

I found the class_value also but couldn't find in the source where it was being used in the dataset. It seems to be added by default if the data_labels are empty.
