Please I want to convert collection data type to array of string
I want to use Naiive bayes algorithm such that the training data is a result of association (consequences and item)
consequences is string (which is not a problem)
the problem is in itemset column whose data type is collection of string [a,b,c,....]
i want to convert this column to be string
I want the training data to be consequences column and itemset column (array of string)
Thanks
