The chocolate
data has been loaded in long format with one row for each alternative in each observed choice. Remember that the Type
, Brand
and Price
describe each alternative and the Selection
variable tells us what the respondent chose. Let's use xtabs()
to find out how often people choose each type of chocolate.
