hi
i am going to practice a simple text mining. there is a CSV file on the 
http://archive.ics.uci.edu/ml/datasets/sms+spam+collection
and i import it to the program. and i am going to change "att2" type from "polynominal" to "text" but there is no "text" choice in the List.
the choices is only: polynominal, bionominal, real, integer, date, date time, time.

please help me solve this problem
thanks a lot

hi @yusuf_nazari - I would recommend just importing the csv with Read CSV and then using the Nominal to Text operator.
