Force Attribute to Nominal (NOT Binomial)
I'm having trouble getting RM to do what I want. Its trying to be too smart but can't see the whole picture. I have a bunch of CSV files that I am appending together. All files have the same attribute columns. Some polynomial attributes only occur as one or two different values per csv file. When I import a CSV and set the attribute to polynomial RM assumes its binomial, however, when I try to append the two example sets it gives me an error saying it cant add another value to a binomial attribute. I know my attributes are polynomial and I use string to nominal, or numerical to nominal with no luck.
Sep 20, 2010 11:28:50 AM SEVERE: Process failed: operator cannot be executed (Cannot map another string for binary attribute: already mapped two strings! First string = <tt>A</tt>, Second string = <tt>B</tt> The third string that was tried to add: <tt>C</tt>).
How can I force the attribute to be polynomial, this should be an option in the type conversion operators. ???
