Hi Engin, If you know what all the levels are, you can specify these in the format command:
Classification_Description<-factor(Classification_Description, levels=c("Total Surplus (+) or Deficit (-)","Borrowing from the Public", "By other means")) This ensures that all the levels are encoded even if one or more levels is missing in the incoming data.
