> How can I create extra observations within clusters?  E.g. an existing data-set with vote-choices `nested in' voters (i.e. a data set in long format), say 5 choices for each voter. How can I create a 6th vote-choice for each voter? (Could be an observation with only missing values or a copy of an existing choice-alternative).
