| predictPairInternal | R Documentation | 
Do not call this directly (which is why it is called "internal"). Instead, call predictPair. Heuristics implement this function in order to be callable with predictPair.
predictPairInternal(object, row1, row2)
object | 
 The object that implements predictPair, e.g. a ttb model.  | 
row1 | 
 The first row of cues (object$cols_to_fit columns), as a one-row matrix.  | 
row2 | 
 The second row of cues.  | 
A number in the set -1, 0, 1, where 1 means row1 is predicted to have a greater criterion, -1 means row2 is greater, and 0 is a tie.
